Because McCain is intensely jealous of the man who won presidency without ever being shot down in a war and be captured by the enemy, and never served a day in any elected office before running for president, while McCain did. I am convinced that intense jealousy and bitterness exacerbated brain cancer. Since POTUS Trump is against the terrorists, McCain as a bonafide anti-Trumper, will be for the terrorists calling them freedom fighters.
I ascribe his position to hatred for Trump and the way he namecalled everyone in the primaries. Trump lost a lot pf republicans because of it, including the Bushes. While we may have laughed and enjoyed it, many people were alarmed and don’t like him because of it.
He was doing it before Trump was running.
I just think he is evil.
But then, he hates me, not because I have done anything to him but because I choose not to fall down and worship.
I tend to have a very low opinion of such people.
