Was John McCain hit on the head one too many times while a POW?

I've never been a fan of the Arizona senator and Republican disgrace. In fact, I primarily refer to him as Senator McVain as he is second only to Chuckie Schumer of New York when it comes to being in love with tv cameras and microphones. For the record, I also consider McVain one of the biggest RINOs this nation has ever seen. These two frauds will do anything, say anything, be anything just
