President Obama's Final 4 revealed

— -- President Barack Obama, the nation's first basketball fan, took marker to bracket with ESPN again at the White House and selected defending tournament champion Louisville, No. 1 overall seed Florida, top seed Arizona and Michigan State to advance to this year's NCAA men's Final Four.

The paths Obama took to arrive at his 2014 Final Four, an event that has come to be known as "Barack-etology", were revealed on SportsCenter at 11 p.m. ET Tuesday. The president's complete picks -- this is the sixth consecutive year he's made them with ESPN's Andy Katz -- will be announced Wednesday on the 9 a.m. ET edition of SportsCenter.

The President has picked three different teams in the "Barack-etology" era to win the men's title -- Indiana (over Louisville in 2013), Kansas (over Ohio State in 2011 and Kentucky in 2010) and North Carolina (over Kentucky in 2012 and Louisville in 2009). His correctly picked national champion was the Tar Heels in '09.

Last year Obama's men's bracket ranked 2,080,996 out of 8.15 million entries in ESPN.com's free ESPN Men's Tournament Challenge, placing him in the 74.4th percentile.

The president correctly picked Louisville to play in the 2013 championship game, predicting a loss to Indiana for the title. In fact, the Hoosiers fell short of the Final Four and the Cardinals defeated Michigan 82-76 in what the president said was "one of the best championship games that any of us have seen in a very, very long time."

Florida in the South Region and Arizona in the West are the only top seeds represented in the president's Final Four. The other top seeds in the tournament are undefeated Wichita State in the Midwest and Virginia in the East. Louisville is the 4 seed in the Midwest and Michigan State is the 4 seed in the East. The Cardinals and Spartans finished their seasons by winning their conference tournaments and are popular picks to make it to the Final Four.

The president is an avid fan of the college game and his hometown Chicago Bulls, and his brother-in-law is the head coach at Oregon State.
