Happy 51st birthday, President Obama! The president's birthday comes as the 2012 election season is heating up, and while campaigns can get ugly with their divisive rhetoric and negative TV ads, a bright spot in the political contest is the support and love we see on display between the candidates and their spouses. We've already looked back at the sweet smooches during this year's Republican primary. As we hope for more love from both the Republican and Democratic couples this year, let's go back in time to 2008, when Sen. Barack Obama and his wife, Michelle, made us collectively say, "Awww." Here are their cutest PDA moments from the last campaign.
