The base has chosen or is choosing a candidate that the establishment says is absolutely unacceptable. And what that means is this marriage of an elite, big business-backed establishment and a blue-collar, downwardly mobile base has really come to a divorce.

Well, it's possible that the new infusion of ad money against Donald Trump kept his margins in Kentucky and Louisiana down a bit. But we're also seeing something that we've never seen in 100 years, which is we are seeing the crackup of a major American political party.

The enthusiasm for [Donald] Trump had gone up. The net result was it made people more supportive of him.

As one conservative intellectual said to me - he said if the choice is between [Joseph] Stalin and [Adolf] Hitler, I'd pick Stalin, meaning Ted Cruz because he's more predictable. So there's real civil war inside the Republican Party.

The lesson is that voters in both parties are in a very anti-establishment, populist mood. Hillary Clinton is the establishment candidate.

Republicans think that [Ted] Cruz would be like Barry Goldwater. He'd lose in a landslide and pull the party down with him. They'd lose Senate and House seats.

If [Hillary] Clinton can come close in those two traditionally red states, it will be because of the diverse, educated populations around Atlanta and Phoenix. And it will be a sign that Arizona and Georgia are on their way to becoming the new battleground states.
