Barack shared his picks live on the network ... channeling his inner Dick Vitale and explaining why he thought he had the perfect bracket.
Obama's bracket was filled out on a 63 by 36-inch whiteboard (which has since been framed) -- and after he made his picks, Barack signed it with a pen.
FYI, Obama's bracket was anything but perfect -- he picked North Carolina to win it all. Instead, Anthony Davis and the Kentucky Wildcats took home the title that season.
While BO's autographed bracket was busted, it's clearly a collector's item -- and will now go to the highest bidder courtesy of Goldin Auctions .
