President Barack Obama's 2012 NCAA Tournament bracket is set. On Tuesday he revealed his Final Four choices, taking the Kentucky Wildcats, Ohio State Buckeyes, Missouri Tigers and North Carolina Tar Heels to reach the semifinals. His full bracket will be revealed Wednesday on ESPN.

Obama has made his bracket public in each of the last four seasons, in what has become a rite of March Madness. He has correctly picked the winner just once, taking the Tar Heels in 2009. In 2010 and 2011 he had the Kansas Jayhawks winning the Big Dance. Obama apparently learned his lesson this year.

This year, Obama is challenging fans to try and beat him by submitting their brackets to his campaign website. Anyone who can beat the president will have their names published on the site.
