The rumors that have existed from when he ran for office four years ago when he pointedly wasn't endorsed by Obama and the all that was heard were hints about "ole Joe", how he couldn't be trusted during off the cuff encounters with voters, and had to constantly have his gaffes cleaned up by his publicity crew. The rumors that have circulated since his numerous stumbling and obvious mentally deficient interviews from his basement as he has won the nomination this cycle. Yes, trump has his gaffes too, but he almost definitely not going to win, so bringing him up as "what about Trump" serves no purpose but to make look as if this is an untouchable subject. I would welcome a public medical eval, but that is almost definitely not going to happen, which means his is probably not 100% clean. Do you want this discussed, or do you want to keep dancing around it so it makes you feel better?
