2008 United States presidential election in Missouri instance of United States presidential election in Missouri
The 2008 United States presidential election in Missouri was held on November 4, 2008, and was part of the 2008 United States presidential election, which took place throughout all 50 states and D.C. Voters chose 11 representatives, or electors to the Electoral College, who voted for president and vice president.
Missouri was won by Republican nominee John McCain by 3,903 votes, a 0.14% margin of victory. Prior to the election, most news organizations considered this state a toss-up, or a swing state. On election day, Missouri was the closest state in 2008, with most news organizations not calling the state until two weeks after the election. A high turnout of voters in the GOP strongholds of Greene County (Springfield) and St. Charles County, combined with Democrat Barack Obama's lackluster performance in the more rural parts of the state, gave the edge to McCain. Since the margin of victory was less than 1%, Obama could have legally called for a recount at no expense to himself, but he ultimately chose not to do so. This was likely because he had already received enough electoral votes to win the presidency which rendered Missouri's 11 electoral votes inconsequential and a recount would have been unlikely to change the outcome.McCain became first Republican to ever win Missouri and lose the presidency and Obama became the first-ever Democrat to win the White House without winning the state. 
Combined with the state's swing to the right in 2000 and 2004 and the further bleeding of Democratic support in white, rural areas, this would be the last time when Missouri was seriously contested and considered to be a swing/bellwether state. This is the first time since 1980 that Missouri voted to the right of North Carolina. The state continued moving deeper and safer into the Republican side four years later and onward, and as such, this is the most recent election when the Republican candidate won less than 50% of the state's popular vote. This was also the last time that Iron County, Jefferson County, Washington County, Ste. Genevieve County, and Buchanan County voted for the Democratic candidate. Nevertheless, Obama's 1,441,911 votes are the most received by a Democratic presidential candidate in the state's history. As of 2020, this is the last election in which Missouri voted to the left of Georgia.
This is the only time Missouri has ever voted Republican while nearby Indiana has voted Democratic. It was the only Midwestern state east of the Great Plains to back McCain in 2008.
