2008 United States presidential election in Missouri

• Missouri Democratic primary, 2008
• Missouri Republican primary, 2008

With the advent of the September financial crisis, Obama began to look viable. John McCain's lead diminished and then disappeared; for several weeks Obama even led Missouri polls.[1] Obama started visiting Republican-leaning states, including Missouri. In one of the more memorable trips of the campaign, he drew crowds of 75,000 at Kansas City and 100,000 at St. Louis.[2] However, John McCain's campaign managed to close the gap and most polls showed a dead tie on and before Election Day.

Although seven of Missouri's eight neighboring states offered the option of early voting, the option was not available in Missouri.[3] Election results must go through a certification process before they are official; local election officials had until November 18 to verify their results and process the provisional ballots cast throughout Missouri.[3]

For the better part of a century, Missouri has been reckoned as the nation's bellwether state. Prior to 2008, since 1904, Missouri had voted for the winner in every presidential election except in 1956 when the state narrowly voted for Democrat Adlai Stevenson of neighboring Illinois over incumbent Republican President Dwight D. Eisenhower. In recent years, however, it has gradually been trending Republican. Although Bill Clinton of neighboring Arkansas won the state with ease during both of his elections in 1992 and 1996, Al Gore and John Kerry considered the Show-Me State a lost cause and did not campaign much there. Although Barack Obama is from neighboring Illinois, at first he likewise put the state as a secondary concern in relation to other swing states such as Ohio and Virginia where he thought he had more of a chance. As his lead diminished in the summer months, he and McCain moved the campaign to more Democratic-friendly states, as McCain maintained a comfortable polling lead in Missouri. Similar hypothetical general match-up polls taken between McCain and Hillary Rodham Clinton, however, showed Clinton always leading in Missouri.

A record 2.9 million Missourians, or 69% of eligible voters, cast their ballots in the general election, about 200,000 more than the previous record in the 2004 election.[32]

On Election Day, John McCain clung to a tiny lead, with absentee and provisional ballots yet to be counted. By Wednesday, November 19, McCain led President-elect Obama by 1,445,813–1,441,910 votes,[3] or approximately 0.14% of the total popular vote in Missouri. CNN called the state for McCain that day.[33] The 2008 presidential election was only the second time in 104 years that it had not voted for the winner of the general election. Missouri was, however, the closest state of the 2008 election.

The Democratic base of Missouri rests in its two largest cities in the west and east – Kansas City and St. Louis, respectively. Obama did extremely well here, winning 83.55% of the vote in St. Louis City and 78.4% in Kansas City. Obama was already a familiar face to St. Louis-area voters, since the St. Louis metro area spills into Illinois. McCain narrowly won the areas in Jackson County outside Kansas City with 49.9% to Obama's 48.8%, but Obama carried the county with 62.14% of the vote due to his strong performance in Kansas City. These two counties, combined with highly affluent and suburban St. Louis County (where he also won 59.50% of the vote), gave him a 300,000 margin over McCain.[34] Obama was also able to carry Boone County, home to the large college town of Columbia (Missouri's fifth-largest city and home of the state's flagship University of Missouri campus), and Jefferson County, which consists of the southern St. Louis suburbs such as Arnold and Festus. George W. Bush narrowly won Jefferson County in 2004 over John Kerry.

However, Obama was unable to substantially improve on Kerry's performance in rural Missouri, which is largely responsible for Missouri's Republican tilt. During the 2008 Missouri Democratic Primary, every rural county in Missouri (with the exception of Nodaway County, home of Northwest Missouri State University in Maryville in Northwestern Missouri), strongly backed Hillary Clinton, often by more than two-to-one margins. Many, if not all, of these counties that Clinton won in the Missouri Primary ended up voting for McCain in the general election. A number of these counties are ancestrally Democratic. However, these counties are very similar in character to Yellow Dog Democrat areas in neighboring Tennessee, Arkansas and Oklahoma. The Democrats in these areas are nowhere near as liberal as their counterparts in St. Louis and Kansas City, and much like their counterparts in neighboring Tennessee and Arkansas, had become increasingly willing to support Republicans at the national level.

Obama lost by an almost two-to-one margin in Southwest Missouri, a Republican stronghold for the better part of a century. This region is entrenched in the Bible Belt and embedded with deep pockets of social conservatives that includes Springfield and Joplin. Even Bill Clinton could not win Southwest Missouri in 1992 despite the fact that he won the state by double digits. Rural Northern Missouri voted against Obama by a three-to-two margin; this region warmly supported Bill Clinton in both of his bids. Obama also lost much of rural Southeast Missouri. Unlike Northern and Southwest Missouri, Southeast Missouri, which strongly backed Bill Clinton both times, is more Democratic at the local and state levels. The region takes in the Lead Belt, the Bootheel and the Ozark Plateau and includes the largest city of Cape Girardeau, a booming college town but also a conservative, upper-middle class community that votes overwhelmingly Republican. Southeast Missouri is socially conservative but economically liberal, consistently electing Democrats at the local and state levels. While Obama ran even in the area southwest of St. Louis, he did worse than John Kerry in the Bootheel.[34] Obama was, however, able to pick up two counties in Southeast Missouri: Washington County (by a margin of five votes) and Iron County. Both counties are predominantly rural and White but are some of the most impoverished counties in the state that are controlled by Democrats at the local and state levels. Both counties gave Hillary Clinton over 70% of the vote in the Missouri Primary as well.

Obama was allowed to request a recount under state law since preliminary results showed a difference of less than 1% of the votes. The request would have had to be granted by the state.[35] However, since Obama already won the election, there had been no indications to suggest that he would request a recount. He ultimately did not request one. As of 2019, this is the closest a Northern Democrat has come to winning Missouri, since John F. Kennedy from Massachusetts did so in 1960, as the previous three Democratic presidential candidates to win the state were all from the South (Lyndon B. Johnson was from Texas, Jimmy Carter from Georgia, and Bill Clinton from Arkansas).

This was the first presidential election that a Democrat won without winning the state of Missouri, a feat Obama would repeat in 2012.

During the same election, Democratic Attorney General Jay Nixon defeated U.S. Representative Kenny Hulshof in a landslide for the Governor's Mansion. Incumbent Republican Governor Matt Blunt did not seek a second term. Nixon performed extremely well in rural Missouri and clinched 58.40% of the total statewide vote compared to Hulshof's 39.49% to become Governor of Missouri. Republicans were, however, able to hold on to the U.S. House seat in Missouri's 9th Congressional District that was vacated by Hulshof in his unsuccessful gubernatorial bid. Republican Blaine Luetkemeyer narrowly defeated Democrat Judy Baker by less than 3 percentage points, in large part due to McCain winning it by 11 points. At the state level, Democrats picked up three seats in the Missouri House of Representatives but Republicans expanded their majority in the Missouri Senate, picking up three seats here. Furthermore, upon the 2008 election, Democrats control all statewide offices but one – Lieutenant Governor Peter Kinder is a Republican. Democrats held on to the office of Attorney General that was vacated by Governor Jay Nixon; Democrat Chris Koster defeated Republican Mike Gibbons 52.83% to 47.17%. Democrats also picked up the office of State Treasurer that was vacated by Republican Sarah Steelman in her unsuccessful bid for the GOP gubernatorial nomination. Democrat Clint Zweifel defeated Republican Brad Lager 50.47% to 47.14%.

Technically the voters of Missouri cast their ballots for electors: representatives to the Electoral College. Missouri is allocated 11 electors because it has 9 congressional districts and 2 senators. All candidates who appear on the ballot or qualify to receive write-in votes must submit a list of 11 electors, who pledge to vote for their candidate and his or her running mate. Whoever wins the majority of votes in the state is awarded all 11 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.[37] An elector who votes for someone other than his or her 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.
