The2008 United States presidential election in Illinois took place on November 4, 2008, and was part of the2008 United States presidential election. Voters chose 21 representatives, or electors to theElectoral College, who voted forpresident andvice president.
Democratic nomineeBarack Obama won his home state by a 25.1 percentage point margin over Republican nomineeJohn McCain. Prior to the election, every major news organization consideredIllinois a state Obama would win, or otherwise a safeblue state. One of the most reliably blue states in the nation, Illinois has not voted for a Republican presidential nominee since1988, whenGeorge 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 theU.S. Senate, won the state in a landslide victory, clinching near 62 percent of the total vote.
As of the2024 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, andVermillion.
As of2024, Obama is the only presidential candidate of either party to win the state with more than 60% of the vote sinceWarren G. Harding in1920, and the only Democrat to do so sinceAndrew Jackson, the Democratic Party's first presidential nominee, in1828 and1832. McCain's 36.78% of the vote is the second-lowest of any major-party nominee since1924, only surpassingGeorge H. W. Bush in1992, when a substantial amount of the vote went toRoss Perot’s candidacy as an independent.
Illinois was one of three states where Obama outperformedFranklin D. Roosevelt in allfour of his runs, as well asLyndon Johnson in his1964 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. Obama's victory in Illinois is the largest ever for a Democrat since the Republican Party became a major party.
For the state-run primaries (Democratic, Republican, and Green), turnout was 40.26%, with 2,940,708 votes cast.[1][2] For the general election, turnout was 70.90%, with 5,522,371 votes cast.[1][2]
State-run primaries were held for both major parties, as well as the Green Party, on February 5.
The2008 Illinois Democratic presidential primary took place onSuper Tuesday, February 5, 2008, with 153 delegates at stake. The winner in each ofIllinois's 19 congressional districts was awarded all of that district's delegates, totaling 100. Another 53 delegates were awarded to the statewide winner,Barack Obama. The 153 delegates represented Illinois at theDemocratic National Convention inDenver, Colorado. Thirty-two other unpledged delegates, known assuperdelegates, also attended the convention and cast their votes as well.
Polls indicated that then-U.S. SenatorBarack Obama was leading then-U.S. SenatorHillary Clinton by double digits in the days before the contest in his home state of Illinois.[3]

It was no surprise that Barack Obama cruised to a landslide victory in Illinois, the state he had represented in theU.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 werewhite and they opted for Obama 57–41; 24% of voters wereAfrican American and they, too, backed Obama 93–5; and 17 percent of voters in the primary wereHispanic/Latino and they narrowly backed Obama 50–49. Obama won all age groups but tied Clinton amongsenior 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-identifiedIndependents. Regarding religion, Obama won every major denomination exceptRoman Catholics, who narrowly backed Clinton 50-48%. Obama wonProtestants by a margin of 58–38, other Christians 79–19, other religions 82–17, andatheists/agnostics 78–21.
Obama performed extremely well statewide and racked up massive victories in his home city ofChicago as well as its suburbs and the metropolitan area. He also won Northern Illinois as well as thecollar counties by substantial victories. Clinton's best performance was in Southern Illinois among the morerural andconservative counties that are majority white, although Obama still won the region as a whole.

Obama won every single pre-election poll, and each by a double-digit margin and with at least 52% (with the exception of anARG poll). The final 3 polls averaged Obama leading 60% to 35%.[26]
Obama raised $35,307,625. McCain raised $7,207,428.[27]
Obama spent $23,319. McCain and interest groups spent $52,865.[28] The Democratic ticket visited the state 13 times. McCain's ticket visited the state twice.[29]
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 from1952 to 1988, save for1960 and1964. However,George H. W. Bush just barely won the state in 1988, and it swung heavily toBill Clinton and the Democrats in1992. 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 toCook County, home toChicago, 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 theQuad Cities andSt. Louis areas. Additionally, the historically Republicancollar counties near Chicago –DuPage,Lake,McHenry,Kane, andWill – have become friendlier to Democrats at the national level.
Barack Obama, the juniorU.S. senator from Illinois at the time of the election, carried the state handily, defeatingJohn 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 sinceFranklin Pierce in1852 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. McLean County voted Democratic for the first time since 1964.[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 had historically voted Republican. He became the first Democrat to winCarroll County since that county was created in 1839, in the process breaking the last remaining Republican streak stretching from initial GOP candidateJohn C. Frémont in1856, and the first Democrat to winBoone County sinceJames K. Polk in1844. McCain did, however, win several of the more rural counties inSouthern Illinois; Obama thus became the first-ever Democrat to win the White House without carryingChristian County. It was not nearly enough, however, to put a serious dent in Obama's 25-point margin in the state.[32] As of the2024 presidential election, this is the last presidential election that a Democrat won all of Chicago's collar counties.
During the same election, seniorU.S. Senator andSenate Majority WhipDick Durbin, a Democrat, was reelected to theU.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 theIllinois House of Representatives.

Technically the voters of Illinois cast their ballots for electors: representatives to theElectoral College. Illinois is allocated 21 electors because it has 19congressional districts and 2senators. 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 afaithless elector.
The electors of each state and theDistrict 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 toBarack Obama andJoe Biden:[34]
