That’s how many presidential elections have been held in U.S. history, including today’s vote.
President Barack Obama’s re-election would mark the fourth Democratic win in the past six presidential elections. A victory by Mitt Romney would mark the second time in the past 120 years that a Republican challenger unseated a Democratic president. Ronald Reagan defeated President Jimmy Carter in 1980.
With polls pointing to a close race, today’s election may be the third time in the past four White House contests in which the winner failed to capture more than 300 electoral votes. George W. Bush won 271 electoral votes in 2000 and 286 electoral votes in 2004. Obama won 365 electoral votes in 2008. A presidential candidate needs 270 electoral votes for victory.
