Politics
After voting for the Democratic nominee in its first two elections in 1848 and 1852 prior to the founding of the Republican Party, Jones County thereafter leaned Republican until 1988. It voted Democrat only four times between 1856 and 1984, in 1912 for Woodrow Wilson when he won with a plurality of the vote after former Republican Theodore Roosevelt ran as the Progressive candidate, leading to a fracture in the national Republican Party, then backing Franklin D. Roosevelt in his two landslide victories of 1932 and 1936, and then supporting Lyndon B. Johnson during his 1964 landslide. From 1988 to 2012, Jones County favored the Democratic nominee in each election. In 2016, Donald Trump flipped the county back to the Republican column, capturing over 56% of the county's vote, the best Republican performance in the county since the 1972 landslide victory of Richard Nixon. Trump increased his vote share to almost 60% in 2020 and increased his margin of victory to over 21%, the first election in the county decided by a margin of over 20% since 1964.

Johnson County, Iowa

Johnson County is located in the U.S. state of Iowa. As of the 2020 census, the population was 152,854, making it the fourth-most populous county in Iowa. The county seat is Iowa City, home of the University of Iowa. Johnson County is included in the Iowa City metropolitan area, which is also included in the Cedar Rapids-Iowa City Corridor Combined Statistical Area.

History
Johnson County was established in December 1837 by the legislature of the Wisconsin Territory, one of thirteen counties established by that body in a comprehensive act. The county's area was partitioned from Dubuque County, and was not initially provided with a civil government, instead being governed by Cedar County officials. It was originally named for the US Vice President Richard M. Johnson (1780–1850). In 2020, the Johnson County Board of Supervisors voted unanimously to change the county's namesake to be Lulu Merle Johnson (1907–1995), the first black woman in the state to earn a doctorate; Vice President Johnson was a slaveowner who had sexual relations with several of his slaves.

The first courthouse in the county was a two-story log cabin structure, built in 1838 in the settlement of Napoleon, about two miles south of the current courthouse. The building stood across from what later would become the James McCollister Farmstead on land later owned by Philip Clark.

After Iowa City was established by fiat as the new territorial capitol of Iowa, the county seat was removed there. The second Johnson County Courthouse, the first in Iowa City, was built on Lot 8 Block 8 of the County Seat Addition to Iowa City in 1842 for $3,690. This location was in the southeast corner of the intersection of Harrison and Clinton Streets. The building was 56 x 28 feet and two stories tall. It was built by James Trimble, who had previously built the first jail.

A third courthouse was built in 1857 in the courthouse square on Clinton Street between Court and Harrison Streets. It was used until 1901, after cracks appeared in its south wall in 1899. The building was apparently built of brick with stone and wood ornamentation.

The Richardsonian Romanesque style courthouse in use today was designed by the firm of Rush, Bowman and Rush of Grand Rapids, Michigan. It was bid at a cost of $111,000 and built by the firm Rowson & Son of Johnson County. The cornerstone was laid in December 1899. The building's tower was based on Henry Hobson Richardson's design for the spire of Trinity Church in Boston. The building was dedicated on June 8, 1901. The currently unused jail that stands to the west of the courthouse was designed by C.L. Wundt of Burlington, Iowa on behalf of the Stewart Iron Works in Cleveland and bid for $14,000.

Geography
According to the U.S. Census Bureau, the county has a total area of 623 sqmi, of which 614 sqmi is land and 9.1 sqmi (1.5%) is water.

About 5.20% of families and 15.00% of the population were below the poverty line, including 8.10% of those under age 18 and 3.80% of those age 65 or over.

Politics
Largely due to the presence of the University of Iowa, Johnson County is considered the most liberal county in Iowa and a stronghold of the Democratic Party, and has always been among Iowa's most Democratic counties since the Civil War. It has been the strongest Democratic county in the state since 1984. This trend predates the recent swing toward the Democrats in counties influenced by college towns. The last Republican to win the county in a presidential election was Richard Nixon in 1960, and the last Republican to even get 40 percent of the county's vote was Ronald Reagan in 1984. The last time the GOP won the county in a gubernatorial election was the 1978 Iowa gubernatorial election. As a measure of how strongly Democratic the county has been, Democrats easily carried it even in the national Republican landslides of 1972, 1984 and 1988, and the county was the only county in Iowa to vote for Democrat Alton B. Parker over Republican Theodore Roosevelt in 1904. In 2020, Joe Biden received the highest percentage of the vote received by any Democrat in the county's history; indeed, by any candidate of any party. In 2024, it was the only county to not vote for Donald Trump in the state's Republican presidential caucuses. Nikki Haley won the county by a single vote.

Johnson County's Democratic bent is just as pronounced at the state level. It was the lone county to vote Democratic in statewide Republican landslides, such as Senator Chuck Grassley's re-elections in 2010 and 2016 or Governor Terry Branstad's re-election in 2014.

In recent decades, politics within the county have become more competitive. From 1992 to 2012, the county has been carried by the Democratic presidential candidate in every election with the exception of 2000, when George W. Bush obtained a plurality. The last Republican to win the county with a majority of the vote was Ronald Reagan in 1984. In the 1996 presidential election, Jefferson County was the only county in the United States to give any (winning) candidate less than forty percent of the vote, with Bill Clinton winning the county 35.1% to Bob Dole's 34.4%. In 2016, Donald Trump received a plurality of the votes in Jefferson County. The county has been the strongest basis of support for the Natural Law Party's presidential campaigns, due to the presence of the Maharishi Vedic City and Maharishi International University.

Iowa County, Iowa

Iowa County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 16,662. The county seat is Marengo.

Iowa County is one of seven counties in the United States to share the same name as the state they are located in. The other six counties are Arkansas County, Hawaii County, Idaho County, New York County, Oklahoma County, and Utah County.

History
Iowa County was formed on February 17, 1843. It was named for the Iowa River, which flows through the county.

The first courthouse was a log cabin built in 1847. This was rented by the county until 1850 when a second courthouse was completed. In 1861 construction of a third courthouse was begun. The current courthouse was built in 1892 after the county had outgrown the previous one.

Iowa County is home to the Amana Colonies, a group of settlements of German Pietists, comprising seven villages. Calling themselves the Ebenezer Society or the Community of True Inspiration (German: die Gemeinde der wahren Inspiration), they first settled in New York state near Buffalo in what is now West Seneca. However, in order to live out their beliefs in more isolated surroundings they moved west, to Iowa County in 1855, living a communal life until the mid-1930s. Today, Amana is a major tourist attraction known mainly for its restaurants and craft shops, and the colonies as a whole have been listed as a National Historic Landmark since 1965.

Geography
According to the U.S. Census Bureau, the county has a total area of 587 sqmi, of which 586 sqmi is land and 1.0 sqmi (0.2%) is water.

The county is intersected by the Iowa River and the north fork of the English River.

Ida County, Iowa

Ida County is a county located in the U.S. state of Iowa. As of the 2020 census the population was 7,005, making it the state's eighth-least populous county. The county seat is Ida Grove. The county was authorized by the Iowa Legislature in January 1851 as a packet of projected counties in unorganized territory of western Iowa. It was named after Ida Smith, the first child of European immigrants to be born in this region.

History
The Iowa Legislature authorized the formation of 49 counties in previously–unregulated western Iowa on January 15, 1851. This date is usually cited as the date of formation of Ida County; however, as there were no inhabitants of that area, no action was taken to form a county government.

On January 12, 1853, the Legislature authorized creation of Woodbury County, and included the proviso that the area of Ida County be included with Woodbury for revenue, election, and judicial purposes. In 1853 there were still no settlers in Ida County's lands.

The county's first permanent settlers (Comstock and Moorehead) arrived in 1856. In 1858 the county government was organized, with John Moorehead appointed County Judge. There were about 40 county residents at that time.

The county's only postoffice, as well as the first courthouse, was operated from Judge Moorehead's house.

The county's first dedicated school building was raised in 1861.

The county's first newspaper, Ida County Pioneer, was started in 1872. The first bank opened in 1876. Railroads arrived in Ida County in 1877, when the Maple Valley branch of the Chicago & North Western Railway was built. This resulted in a flood of settlers, and within five years, nearly all the available land had been purchased.

Geography
According to the U.S. Census Bureau, the county has a total area of 432 sqmi, of which 432 sqmi is land and 0.5 sqmi (0.1%) is water.

Humboldt County, Iowa

Humboldt County is a county in the U.S. state of Iowa. As of the 2020 census, the population was 9,597. The county seat is Dakota City. The county was created in 1857 and named in honor of Alexander von Humboldt.

Founding
Iowa's entry to the union was approved by Congress on March 3, 1845, with statehood beginning on December 28, 1846, following approval of the state's constitution and boundaries. In order to establish county government across the state, the Iowa General Assembly passed an act on January 15, 1851, which created fifty counties in the half of the state where county government had not yet been established. Humboldt County was created by this act, containing its present area, as well as four townships in present-day Webster County: Jackson, Deer Creek, Badger, and Newark. It was named after Alexander von Humboldt. On January 21, 1855, an act merged the northern half of Humboldt County and Bancroft County into Kossuth County, with the southern half of Humboldt County merging into Webster County.

The Sixth General Assembly passed another act, reestablishing Humboldt County. The act was passed on January 28, 1857, and went into effect on February 26. However, an error omitted the lower four townships (Jackson, Deer Creek, Badger, and Newark) from returning to Humboldt County. The error was not caught until the next session of the general assembly, and the general assembly passed a bill redefining Humboldt County to include the four townships on March 11, 1858. However, in the interceding time, the Constitution of Iowa came into effect, including the provision that "future laws altering county boundaries should be submitted to a vote of the people of the counties concerned and must be approved by them before going into effect". In a court case originating in the disputed area, the Iowa Supreme Court was asked to decide which county court had original jurisdiction. In their clarification, they ruled the March 11, 1858, clarification of Humboldt County's boundaries unconstitutional, as it had not been submitted to a public vote in the counties involved. In his decision, Chief Justice Ralph P. Lowe wrote, "We are compelled to conclude that township 90, in ranges 27 to 30, west of the 5th principal meridian, is still in and forms a part of Webster county. Of course we can pay no attention to conjectural surmises and vague suspicions, which have been made and entertained in relation to some unfairness which may have been practiced in the final passage of the act of 1857, creating the county of Humboldt. If such was the case, no evidence of the fact has been presented to us." The "vague suspicions" include a rumor that John Duncombe of Fort Dodge (namesake of Duncombe, Iowa and plaintiff in the lawsuit) had tricked Humboldt County into ceding the southern four townships to Webster County "on loan", or was otherwise responsible for the "error".

In 1872, Humboldt College was opened and closed in 1916 because there was no agreement with the county about taxation.

Geography
According to the U.S. Census Bureau, the county has an area of 436 sqmi, of which 434 sqmi is land and 1.3 sqmi (0.3%) is water.

Unlike all counties to its east and west, Humboldt County has only 12 townships. Although founded with the standard 16 townships on January 15, 1851, the county was removed from existence in 1855.

 * Wright County (east)
 * Webster County (south)
 * Pocahontas County (west)

Ecology
Humboldt County is located entirely within the Des Moines Lobe of the Western Corn Belt Plains ecoregion, as defined by the United States Environmental Protection Agency (EPA). One of the flattest regions in Iowa, the Des Moines Lobe ecoregion is a distinctive area naturally defined by Wisconsin glaciation but modified by humans for extensive agriculture. In general, the land is level to gently rolling with some areas of relief defined by glacial features like moraines, hummocky knobs, and kettles, and outwash deposits. The lobe does not have any loess deposits like the Loess Hills to the west.

The stream network is poorly developed and widely spaced, with major rivers carving valleys that are relatively deep and steep-sided. Almost all of the natural lakes of Iowa are found in the northern part of this region (the Iowa Great Lakes). Most of the region has been converted from wet prairie to agricultural use with substantial surface water drainage. Only a small fraction of the wetlands remain, and many natural lakes have been drained as a result of agricultural drainage projects via drainage tiles or ditches.

Hydrology
Humboldt County is located within the Des Moines River watershed. The East and West Forks of the Des Moines River merge at Frank Gotch State Park in southern Humboldt County. The eastern part of Humboldt County is within the Boone River watershed, a tributary of the Des Moines.

Protected areas
While Humboldt County does not have any state parks, it has county parks. South of Humboldt is Frank A. Gotch County Park. It is named for Frank Gotch, a world-champion, undefeated wrestler from Humboldt. The park is near his childhood farm and is also home to the confluence of the East and West Forks of the Des Moines River. The park features campgrounds and a well-known converted railroad bridge used by the Minneapolis and St. Louis Railway. The bridge is part of the Three Rivers Trail, a converted rail route that runs from Eagle Grove west to Rolfe.

Near Bradgate is the Willow Access Area. The terrain is very wooded. In south Rutland is Rose Mill Park. The area can be used for camping and also has access to the Rutland Dam and West Fork of the Des Moines River. The dam is being restored, and most of the park is new. The river is known for its forested limestone bluffs and grassy banks.

Further downriver near Humboldt is Oxbow Park, which contains boating access ramps and much scenic open space. The park's southern border is Iowa Highway 3, and south of that is Joe Sheldon County Park. The park is split into two sections, one mostly for camping and one focused on recreation. There is access to the West Fork of the Des Moines River from the lower part of the park.

Continuing along the river, the Lake Nokomis area begins, popular for its woods and small ponds. The Cottonwood Trail also runs through the area.

West of Livermore, Lott's Park allows access to Lott's Creek. The park has many benches and picnic tables. South of Ottosen is the Ottosen Marsh State Game Management Area, colloquially the Ottosen Potholes. East of Dakota City is the Dakota City River Park, near an old dam and the Humboldt County Historical Museum. Near the unincorporated community of Pioneer is the Pioneer Prairie Pothole Wildlife Area.

Politics
Grundy County has long been one of the most consistently Republican counties in Iowa. The county has only voted for a candidate of a different party four times since the county was founded in 1851. The first occasion was in 1912, when former Republican Theodore Roosevelt won the county as the Progressive candidate. During his two landslide victories of 1932 and 1936, Franklin D. Roosevelt became the first Democrat to win Grundy County in its history. The final time a non-Republican candidate carried the county was in 1964, when Lyndon B. Johnson won in a nationwide landslide. No Democratic candidate has ever received more than 60% of the vote in the county, and in the last twenty elections (beginning in 1944), the Republican obtained at least 60% of the vote in fifteen of them, and the Republicans have hit at least 65% in nine of the twenty elections in that span.
