Tom Brady -- Political Endorsement from Patrick Kennedy?!

He already won the Super Bowl ... and the MVP award ... but could Tom Brady also win an election one day???

Don't count him out ... so says former Congressman Patrick Kennedy -- who says Tom's got all the right qualities for a career in politics.

Kennedy (Dem-Rhode Island) was out in D.C. when he joked that Brady could win any election in the country right now (except for Seattle) ... and praised the guy as a real stud in the community.

For the record, Brady has said he's thought about a political career in the past ... but is leaning toward staying out of it.
