Just 0.35% of more than 5 million March Madness brackets filled out on CBSSports.com correctly guessed the Final Four of Kentucky, Louisville, Kansas and Ohio State. Of ESPN.com's nearly 6.5 million entries, just 0.4% had it right.
President Obama seems to have got it right though. His bracket is doing quite well: He's in the 96th percentile of ESPN.com's contest behind a half-correct projected Final Four. Like nearly a fifth of the ESPN.com entries, however, Barry O'Bomber had the Tar Heels winning it all, so his ranking will take a hit next weekend. You track Obama's bracket here, and ESPN.com's overall leaders here.
Kentucky, the only number one seed to make the Final Four, is also dominating the March Madness social buzz, scoring 100 out of 100 possible points on Mashable's mRank leaderboard. The Wildcats are also an extremely popular pick online to take home the national title. In the CBSSports.com challenge, 58% of total brackets pick the them to win the championship, and 79% had them in the Final Four.
Despite a rash of first round upsets -- including Duke, rated as the tournament's most exciting team, losing its first game to a 15 seed -- this year's Final Four doesn't include any huge underdogs like the last two did. And that shows in the numbers.
While only 0.4% of ESPN.com's 6.45 million entries got the Final Four right, that still comes out to more than 25,000 brackets. The total number last year, when Virginia Commonwealth came from nowhere to crash the party: 2 of 5.9 million.
