John McCain, according to the Huffington Post, was especially not amused by one of Cruz's crazier moments:

"If you go to the 1940s, Nazi Germany," Cruz said. "Look, we saw in Britain, Neville Chamberlain, who told the British people, 'Accept the Nazis. Yes, they'll dominate the continent of Europe but that's not our problem. Let's appease them. Why? Because it can't be done. We can't possibly stand against them.'"

"I resoundingly reject that allegation," McCain said. "That allegation, in my view, does a great disservice. A great disservice to those brave Americans and those who stood up and said, 'what's happening in Europe cannot stand.'"

The Huffington Post also quotes McCain as saying that the fight on Obamacare was over, that Republicans "fought [Obamacare] as hard as we could in a fair and honest manner and we lost."
