Milbank: McCain relished being the 'antidote' to Donald Trump

Powerhouse Politics podcast hosts share their favorite moments with McCain.

Karl joked that the “third-tier” reporters, like himself, who covered the Arizona Republican on McCain's Straight Talk Express campaign bus, were his “base.”

"He had no money, so he decided that his strategy would be to basically use free media be surrounded by the press all the time. So, he had that bus -- the Straight Talk Express. And I'll tell you, I think I lived on that damn thing for months. All day long, morning until night. Almost all the time, on the record," Karl said.

Klein agreed.

“Any reporter of our generation, or anyone who's covered politics for the last couple of decades, has McCain stories because one of the things, one of the tremendous things about covering John McCain, is that he actually liked interactions with reporters. He enjoyed the engagement. He enjoyed the teasing, and the back and forth, and the cat and mouse involved in all of it.”

Klein recounted a story about bringing his five-year-old son to the green room of a TV studio and watching McCain kindly entertain his young son with a coloring book and hot chocolate.

“When I came back they were coloring together, and they both had hot chocolates. It just struck me that there was a guy -- you know an absolute legend -- a man who had done everything in politics. And there was just no pretense around it. He was just a guy talking to a kid and passing the time,” Klein said.

Washington Post columnist Dana Milbank, a veteran reporter who also covered McCain during the Straight Talk Express years, talked about his memories.

Milbank added that watching President Trump demonize McCain at his rallies, and now refusing to fully honor McCain’s legacy, only highlights the differences between the two men. “So I suspect that having Trump -- who is really sort of a polar opposite -- probably gave him an extra spring in his step these last couple years.”
