This just in from the Associated Press:

Republican John McCain has defeated President-elect Barack Obama in Missouri _ the last state to be decided in the 2008 presidential election.
McCain’s narrow victory over Obama breaks a bellwether streak in which Missourians had picked the winning presidential candidate in every election since 1956.
With all jurisdictions reporting complete but unofficial results, McCain led Obama by 3,632 votes Wednesday out of more than 2.9 million cast _ a margin of 0.12 percentage points.
