Do we know that McCain was “wasting away” in the Vietnam Hilton. Some say he was well fed and was sent ‘visitors’ to his Hilton.
But that heroism should stand on its own. Yet McCain has shamelessly exploited it for his own career (as his books show).
He also has wrong-headed notion that using the military is the answer to everything. McCain fashions himself as a swash-buckling "maverick", but in truth he's a loose cannon on deck. He lacks common sense, and has failed to address veterans issues that really mattered with all his grandstanding.
McCain is a very dangerous man to our republic. Trump must find a way to muzzle him -- and Trump will, as he did successfully in the campaign.
