DuPage County, Illinois

History

Prior to European-American settlement, the area that is now DuPage County was inhabited by the Potawatomi people. By 1800, the Potawatomi had established 4 major villages along local rivers within the county, and had a network of trails crisscrossing the area. The first European-American settlers arrived in what is now DuPage County in 1832, and the Potawatomi population was forced out of the region only one year later after ceding their land in the Treaty of Chicago. DuPage County was officially formed on February 9, 1839, out of Cook County. The county took its name from the DuPage River, which was, in turn, named after a French fur trapper, DuPage. The first written history to address the name, the 1882 History of DuPage County, Illinois, by Rufus Blanchard, relates:

The first white settler in DuPage County was Bailey Hobson who, with Lewis Stewart, built a house in 1831 for the Hobson family at a site about 2 mi south of present-day downtown Naperville. Hobson later built a mill to serve surrounding farmers. Today, the Hobson house still stands on Hobson Road in Naperville, and the location of the mill is commemorated with a millstone and monument in today's Pioneer Park.

According to the U.S. Census Bureau, the county has a total area of 336 sqmi, of which 327 sqmi is land and 8.9 sqmi (2.6%) is water. The DuPage River and the Salt Creek flow through DuPage County. According to the Forest Preserve District of DuPage County, the highest point in the county is located at the Mallard Lake Landfill, which at its highest point is 982 ft above mean sea level.

In the 1980s, DuPage County also had another major attraction, Ebenezer Floppen Slopper's Wonderful Water slides in Oakbrook Terrace, which today, stands abandoned and neglected.

The Illinois Prairie Path, a 61 mi rail-to-trail multi-use path, runs through Cook, DuPage and Kane Counties. It intersects with the Great Western Trail at several points, as well as the Fox River Trail at a few points.

Government

The county is divided into six districts. Each district elects three members to the County Board in staggered two-year and four-year terms. The Chairman of the County Board is the chief executive officer of DuPage County, and is elected countywide every four years.

DuPage County is part of Regional Office of Education #19 which is coterminous with the county's corporate boundaries.

As of December 2022, the DuPage County Board is controlled by the Democratic Party by a 12 to 6 margin.

Politics

DuPage County was historically a stronghold of the Republican Party, and a classic bastion of suburban conservatism. In recent years, DuPage County has joined other inner-ring suburbs outside large U.S. cities trending Democratic in presidential election years since the 1990s. The county also leans increasingly Democratic in state and local politics. In the 2018 Illinois gubernatorial election, J. B. Pritzker became the first Democratic candidate for the governorship to win the county in nearly 100 years. DuPage County voters backed Pritzker in his 2022 re-election bid by a large margin.

National politics

The county supported Barack Obama, a Chicago resident, in 2008 and 2012 (albeit narrowly in 2012). Obama was the first Democratic presidential nominee to win the county since Franklin Pierce in 1852. The only time prior to 2008 that a Republican had failed to win the county was in 1912, when the GOP was mortally divided and former president and Progressive Party nominee Theodore Roosevelt won over half the county's vote. As a measure of how Republican DuPage was at the time, it was one of the few counties where Franklin D. Roosevelt was shut out in all four of his successful campaigns, and it also rejected Lyndon Johnson in his 44-state landslide of 1964. FDR and LBJ were the only Democrats to win 40 percent of the county's vote in the 20th century, and Bill Clinton was the only other Democrat to come remotely close to that figure.

DuPage County was historically a fiscally and socially conservative Republican stronghold, though in recent years has become more politically liberal especially on issues of race and immigration. In recent years, DuPage County has been shifting more Democratic; it has not supported a Republican for president since George W. Bush in 2004. Obama carried it four years later with a margin almost as large as Bush's 2004 total. The Democratic trend culminated with Joe Biden winning nearly 58% of the vote in 2020. Donald Trump was the first Republican nominee for president since 1912 to get less than 40% of the DuPage County vote, both in the 2016 and 2020 general elections. Many DuPage County communities which normally vote Republican, including but not limited to Naperville, Lisle, Wheaton, Glen Ellyn, Carol Stream, Downers Grove, and Elmhurst did not support Trump in 2016. In December 2019, shortly after the U.S. House of Representatives voted to impeach Donald Trump, Carol Stream-based Christianity Today published a controversial editorial calling for the removal of Trump from office, citing the need to hold him to the same standards to which they held Bill Clinton in the 1990s (who was the last Democratic nominee for president to get less than 40% of the DuPage County vote).

In the U.S. House of Representatives, DuPage County is in the 3rd, 4th, 6th, 8th, 11th and districts. In the 2018 general election, despite the county's historical Republican dominance, Democrats won every congressional district within the county.

Local politics

Republicans historically controlled local politics in DuPage County from the nineteenth century until modern times. During the twentieth century, Democrats only held countywide office twice. In 1934 William Robinson was elected Circuit Clerk and Arthur Hellyer was elected Treasurer. That year also saw the first ever Democratic majority county board and only such majority that century. Robinson and Hellyer each served one term; Robinson lost his bid for a full term in 1936 and Hellyer left the Treasurer's office to make a failed bid for probate judge in 1938. In 2018, as part of a larger suburban realignment, Democratic candidate Jean Kaczmarek won the election for County Clerk and Daniel Hebreard won the President of the Forest Preserve District of DuPage County.

During that same period Democrats were sporadically elected to the county board and township government. In 1972, Don Carroll was elected to the County Board. In the Democratic wave of 1974, Jane Spirgel, Mary Eleanor Wall, and Elaine Libovicz were elected. All four were from the northeastern portion of DuPage, which at that time was the most Democratic region of the county. Eventually, Republicans regained all seats on the board when Jane Spirgel ran for Illinois Secretary of State with Adlai Stevenson III under the Solidarity Party banner. In 2000, Linda J. Bourke Hilbert was elected. Like her 1970s counterparts, she was from the northeastern portion of the county. During the 2008 Democratic wave, three Democrats were elected to the board. After the initial Obama wave, Republicans reasserted themselves on the board and by 2017 Democrats held only one of the eighteen board seats. In the 2018 general election, Democrats won seven seats as well as the offices of County Clerk and Forest Preserve District President.

In 1973, a slate of Democrats took eight of nine offices in Addison Township. This feat would not be replicated until 2017 when Democratic candidates won a majority of offices in Naperville and Lisle townships. Between these two victories, Democrats only held two township offices. Mark Starkovich served as York Township Supervisor from 1989 to 1993 and Martin McManamon has served as Wayne Township Highway Commissioner since 2013.

In 2020, Democrats won control of the DuPage County Board, expanding on their 2018 lead. In 2022, Democrats expanded their majority in the County Board to 11 seats out of 18. Concurrently, Democrat Deb Conroy was elected as the chairman of the County Board.

Transportation

Main article: List of county roads in DuPage County, Illinois

Airports

A small portion of O'Hare International Airport is located inside the county, as are several small airports, including DuPage Airport.

Public transit

Regional Transit Authority

DuPage is served by a number of modes of public transit overseen by the Regional Transportation Authority. Pace operates the bus system within the county. DuPage County is also well-covered by Metra, the Chicago-area commuter rail system. Three of Metra's eleven lines pass through the county: Milwaukee District West Line, Union Pacific West Line, and BNSF Line. Nineteen Metra stations are located within DuPage County.

Extending the O'Hare terminus of the Chicago "L"'s Blue Line westward to Schaumburg has been a topic of discussion for years. After planning for the Metra STAR Line nixed the initial route which went exclusively through Cook County, an option that would include two stations in DuPage County (Bensenville/ Wood Dale, as well as Itasca) became the preferred alternative. After resistance from Chicago Mayor Richard M. Daley, this plan failed to come to fruition.

In 2008, the Regional Transit Authority included an 13.3 mi extension of a different branch of the Blue Line, from its current western terminus at Forest Park to Yorktown Center in Lombard, Illinois. Several feeder bus services would also be implemented in this plan. The prospect of this extension was also listed in the Chicago region's 2030 master plan.

Amtrak

Amtrak also serves the county at Naperville station. The Illinois Zephyr and Carl Sandburg run from Chicago to Quincy, the Southwest Chief from Chicago to Los Angeles, and the California Zephyr runs from Chicago to Emeryville, California.

Major highways

DuPage County is served by five Interstate Highways, two U.S. Highways, and nine state highways.

North–south roads (from west to east) include: IL 59 (Neltnor Boulevard), IL 53, I-355 (Veterans Memorial Tollway) and IL 83 (Kingery Highway).

I-294 partially enters DuPage County on its eastern border between Westchester, in Cook County, and Oak Brook, in DuPage County. Only the southbound lanes enter the county though. Historic U.S. Route 66 crosses through the southeast portion of the county near Darien and Willowbrook.
