Literally one day after winning his primary, Sen. John McCain (R-Ariz.) gave up on Donald Trump. In fact, McCain now sounds a bit like he’s betting on Trump losing — or, at least, looking like a loser for the rest of the campaign season — to help him win a sixth term in the Senate.

In a gauzy, five-minute YouTube video released Wednesday, McCain looks directly at the camera and says: “My opponent, Representative Ann Kirkpatrick, is a good person. But if Hillary Clinton is elected president, Arizona will need a senator who will act as a check — not a rubber stamp — for the White House.”

In two sentences, McCain is betting that people believe Clinton is going to win in November. And that many voters in Arizona who don’t like Trump aren’t keen on Clinton either.
