Super Bowl 50 -- Trump Picks Peyton ... 'He's a Good Guy'

His Trumpness has officially picked sides for the Super Bowl -- pledging allegiance to the Denver Broncos ... because he says Peyton Manning is a "good guy."

Donald was on "Face The Nation" this weekend -- when he was asked for his stance on the Denver vs. Carolina game ... and Trump was quick to explain why he's going with Denver.

"I very much have always liked Peyton Manning," Trump said ... "He's a very good guy. I know him. So I have to go with the person who I know."

Trump says he knows the Panthers are the "hot team" -- and Cam Newton is "doing great" ... but when push comes to shove, he's siding with his pal Peyton.

Makes you wonder ... who he was rooting for last week when his friend Peyton took on his buddy Tom Brady?
