Donald Trump (45) won't do one ... but Barack Obama (44) is still filling out his March Madness bracket -- and he's picking Michigan State -- a 3 seed -- to win it all!!!
"Just because I have more time to watch games doesn’t mean my picks will be better," Obama wrote ... "but here are my brackets this year."
So, who's he got? There are some upsets in there including Loyola-Chicago (11) over Miami (6).
He also has Texas (10) over Nevada (7).
Obama also has Syracuse (11) beating Arizona State in the playoff game and then beating TCU (6).
His Final Four -- Virginia (1), North Carolina (2), Villanova (1) and Michigan State (3).
The official tournament starts Thursday.
Of course, President Obama went to Harvard ... but they suck at basketball and didn't make the NCAA tourney.
Maybe next year?
