-Him refusing public funding.
Some, it does make him look like a hypocrite.
-His old campaign logo looking too much like the Presidential seal.
No, and the sort of people dumb enough to be swayed by this probably don't couldn't recognize the seal if you showed it to them.
-Giving his acceptance speech in a stadium.
This will HELP.
-Those "bitter" comments made 4 months ago (and almost 9 months before the election.)
This will hurt the most, possibly enough to cost him Ohio.
-The DNC FL/MI crisis that even Hillary accepted the resolution on and no one outside of Hillary is 44 cares about anymore.
No.
