President Barack Obama is going back to Carolina in his NCAA tournament bracket.

The president, who correctly picked North Carolina to win the 2009 NCAA championship, has the Tar Heels as the team to beat in his 2012 bracket, which was unveiled Wednesday.

Republican presidential candidate Mitt Romney said he won't be filling out a tournament bracket.

"I'm not plugged in well-enough this year to do that," Romney said Tuesday during a brief exchange with reporters traveling with him in Missouri.
