Tom Brady -- I Love Donald Trump ... Not Sure If I'll Vote for Him Tho

Tom Brady says he's NOT ready to fully commit to Donald Trump -- claiming he's a huge fan of the guy ... but he's not 100% convinced he's earned the Brady vote for president.

After a photo surfaced showing a Trump hat in Brady's locker, the QB appeared on WEEI in Boston and explained it was a gift from The Donald himself.

"He sent it to me via [Robert Kraft]," Brady said ... "I’ve known [Trump] since 2002 where I judged one of his beauty pageants."

But when asked straight up if he's voting for Donald, Brady replied, "I don’t know. That’s a good question. Honestly he’s a great friend ... spent a lot of time golfing together."

So, maybe.

Brady was also asked about reports that his marriage with Gisele was on the rocks.
