McCain could not be acting more like a douchebag.
McCain is an egotistical PITA who should have had the decency to retire after the end of his last term. However, I don't see what you guys are talking about. I've looked at McCain's quotes and what I see is the leftist media trying to stir things up by making up things. And you fell into the trap.
The article in this thread bears this out: John McCain's Fake Fight With Ted Cruz Over Guns on Military Bases (Bloomberg News Defends Cruz!)
This looks like another case of "I'll believe anything said about [insert name of person you don't like] as long as it's bad."
That's between quotation marks, and douchy.
Ted's original remarks, OTOH, were misrepresented, as Bloomberg reported.
