Look Septic, nobody can or should argue over the man's service to his nation, especially in light of the hell he went through as a POW and the fact he served during a time when service wasn't the most popular of options for anyone. He deserves all the respect in the world for that.
However...
I find it completely hard to believe you are supporting someone who's been in Congress longer than you've been getting excited at the lingerie section of the JC Penny catalog. Or quite possibly been alive (not sure how old you are). If you are as independent as you say you are, you would despise that simple fact alone and realize he's been in Congress far, far, far too long. And the only reason you take up for him at this point is your frothing at the mouth anti-Trump attitude. Yes, he voted against that turd of an ACA "replacement." But that's about the extent of being anti-GOP. Because you can't point to any significant legislation prior to Trump he voted against without a long drawn out search.
You brought McCain into this conversation. He's one of the head alligators in the swamp. And in reality, he's part of the problem. You just can't bring yourself to admit it because he's anti-Trump and you love him for it.
