PHOTO: Barack Obama likes Kentucky to win March Madness, Davidson to make Sweet Sixteen

Bracketology is sweeping the nation and the country's most popular NCAA tournament bracket is all filled in, and it's pretty safe.

President Barack Obama filled out his March Madness bracket and, like many, he sides with Kentucky, picking the Wildcats to beat Villanova to win the national championship.

Obama, who named a correct winner just once in his two terms – North Carolina in 2009 – likes Davidson to be the Cinderella team and make a run before falling to Iowa State in the Sweet Sixteen.

His Final Four features Kentucky, Villanova, Duke and Arizona.

It didn't take long for the president's bracket to be busted, however, as he took BYU to meet and defeat Xavier in the tournament's second round. The Cougars lost to Ole Miss in the First Four.
