Barack Obama
On April 4, 2011 Obama said that he would run for re-election for a second term in 2012 in a video titled "It Begins with Us" that he posted on his website and filed election papers with the Federal Election Commission. He was officially nominated as his party's nominee on September 6, 2012. Mitt Romney was officially nominated as his opponent by the Republican party on August 30, 2012. While the election results were very close, Obama easily won the electoral college votes he needed to win a second term. Obama and Romney spent more than $2 billion on advertising during the election campaign.
