President before election George W. Bush Republican Elected President Barack Obama Democratic

The 2008 United States presidential election in Illinois took place on November 4, 2008, and was part of the 2008 United States presidential election. Voters chose 21 representatives, or electors to the Electoral College, who voted for president and vice president.

Democratic nominee Barack Obama won his home state by a 25.1 percentage point margin over Republican nominee John McCain. Prior to the election, every major news organization considered Illinois a state Obama would win, or otherwise a safe blue state. One of the most reliably blue states in the nation, Illinois has not voted for a Republican presidential nominee since 1988, when George H. W. Bush narrowly carried the state. In 2008, continuing that trend, it appeared that a generic Democratic presidential nominee could have easily won Illinois; it was no surprise then that Obama, who represented Illinois in the U.S. Senate, won the state in a landslide victory, clinching near 62 percent of the total vote.

As of the 2024 presidential election ^[update] , this is the last time a Democrat won the following counties: Boone, Bureau, Cass, Calhoun, Coles, Gallatin, Grundy, Kankakee, LaSalle, Macon, Macoupin, Madison, Mason, McDonough, McHenry, Montgomery, Pulaski, Sangamon, Schuyler, Stephenson, and Vermillion.

As of 2024, Obama is the only presidential candidate of either party to win the state with more than 60% of the vote since Warren G. Harding in 1920, and the only Democrat to do so since Andrew Jackson, the Democratic Party's first presidential nominee, in 1828 and 1832. McCain's 36.78% of the vote is the second-lowest of any major-party nominee since 1924, only surpassing George H. W. Bush in 1992, when a substantial amount of the vote went to Ross Perot’s candidacy as an independent.

Illinois was one of three states where Obama outperformed Franklin D. Roosevelt in all four of his runs, as well as Lyndon Johnson in his 1964 landslide. The others were rapidly Democratic-trending Vermont and Delaware, the latter being the home state of Joe Biden, Obama's running mate. This would be the last election in which the margin in Cook County was not the deciding factor in a statewide victory

Analysis

It was no surprise that Barack Obama cruised to a landslide victory in Illinois, the state he had represented in the U.S. Senate since 2005. He enjoyed massive support in his state among all demographics. According to exit polls, 57% of voters in the Illinois Democratic Primary were white and they opted for Obama 57–41; 24% of voters were African American and they, too, backed Obama 93–5; and 17 percent of voters in the primary were Hispanic/Latino and they narrowly backed Obama 50–49. Obama won all age groups but tied Clinton among senior citizens aged 65 and over. He won all voters in the state of all educational attainment levels as well as income/socioeconomic classes. He won all ideological groups and voters from both parties as well as self-identified Independents. Regarding religion, Obama won every major denomination except Roman Catholics, who narrowly backed Clinton 50-48%. Obama won Protestants by a margin of 58–38, other Christians 79–19, other religions 82–17, and atheists/agnostics 78–21.

Obama performed extremely well statewide and racked up massive victories in his home city of Chicago as well as its suburbs and the metropolitan area. He also won Northern Illinois as well as the collar counties by substantial victories. Clinton's best performance was in Southern Illinois among the more rural and conservative counties that are majority white, although Obama still won the region as a whole.

By virtue of Green Party candidate Rich Whitney's performance in the 2006 Illinois gubernatorial election, the party had earned the right to have a state-run primary in 2008.

Analysis

For most of the second half of the 20th century, Illinois was reckoned as a Republican-leaning swing state. It voted Republican in every election from 1952 to 1988, save for 1960 and 1964. However, George H. W. Bush just barely won the state in 1988, and it swung heavily to Bill Clinton and the Democrats in 1992. Since then, Democrats have won the state by fairly comfortable margins, and it is now reckoned as the most solidly Democratic state in the Midwest.

The Democratic trend in Illinois can be largely attributed to Cook County, home to Chicago, which makes up about 41.2% of the state's total population. ^[30] While Chicago has been a Democratic stronghold for decades, the suburban areas of Cook County have historically tilted Republican. However, the brand of Republicanism in the suburbs has historically been moderate, and these areas swung Democratic as the national party moved more to the right. Democrats also do very well in the Illinois portions of the Quad Cities and St. Louis areas. Additionally, the historically Republican collar counties near Chicago – DuPage, Lake, McHenry, Kane, and Will – have become friendlier to Democrats at the national level.

Barack Obama, the junior U.S. senator from Illinois at the time of the election, carried the state handily, defeating John McCain of Arizona by a margin of 1.38 million votes. Obama carried his home county, Cook County, with roughly 76% of the vote, the highest percentage of any Democratic presidential candidate since its incorporation in 1831. He also swept all five collar counties, becoming the first Democratic candidate since Franklin Pierce in 1852 to do so, with DuPage, Kendall, Lake, and Will giving him double-digit margins. Notably, DuPage, Kane, Kendall, and McHenry had not supported a Democrat for president since that election. ^[31] Obama improved on Kerry's performance enough that he would have prevailed in the state even if the Democratic stronghold of Cook County had its votes excluded, albeit by a narrower margin of 1,790,324 votes to McCain's 1,543,443 or 53.7% - 46.3% of the two-party vote. This is the only time in the 21st century that the Democratic candidate has done so.

Obama also did very well in several rural counties that historically voted Republican. He became the first Democrat to win Carroll County since that county was created in 1839, in the process breaking the last remaining Republican streak stretching from initial GOP candidate John C. Frémont in 1856, and the first Democrat to win Boone County since James K. Polk in 1844. McCain did, however, win several of the more rural counties in Southern Illinois; Obama thus became the first-ever Democrat to win the White House without carrying Christian County. It was not nearly enough, however, to put a serious dent in Obama's 25-point margin in the state. ^[32] As of the 2024 presidential election, this is the last presidential election that a Democrat won all of Chicago's collar counties.

During the same election, senior U.S. Senator and Senate Majority Whip Dick Durbin, a Democrat, was reelected to the U.S. Senate with 67.84% of the vote over Republican Dr. Steve Sauerberg who received 28.53%. At the state level, Democrats picked up three seats in the Illinois House of Representatives.

Electors

Main article: List of 2008 United States presidential electors

Technically the voters of Illinois cast their ballots for electors: representatives to the Electoral College. Illinois is allocated 21 electors because it has 19 congressional districts and 2 senators. All candidates who appear on the ballot or qualify to receive write-in votes must submit a list of 21 electors, who pledge to vote for their candidate and the candidate's running mate. Whoever wins the majority of votes in the state is awarded all 21 electoral votes. Their chosen electors then vote for president and vice president. Although electors are pledged to their candidate and running mate, they are not obligated to vote for them. ^[33] An elector who votes for someone other than their candidate is known as a faithless elector.

The electors of each state and the District of Columbia met on December 15, 2008, to cast their votes for president and vice president. The Electoral College itself never meets as one body. Instead the electors from each state and the District of Columbia met in their respective capitols.

The following were the members of the Electoral College from the state. All 21 were pledged to Barack Obama and Joe Biden: ^[34]
