Ted Cruz is a small-government conservative.

Yes, the presidential race is very close, and some public polls show it getting closer as we go into the final hours, but in one sense it's actually been stable for months.

Well, we had a bunch of primaries and caucuses on the Democratic side. Bernie Sanders won the Nebraska and Kansas caucuses. That keeps his campaign alive. But Hillary Clinton won Louisiana, which was the big prize of the night, so she ended up winning more delegates than he did yesterday.

There's disgust with what people called a broken political system, and they're really angry at elites, whether it's the Republican establishment or particularly the media who they feel look down on them, tell them they're bigots.

Hillary Clinton is also not a very exciting, inspiring candidate to a lot of the left-leaning Democratic base, especially in Iowa.

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.

Many people feel he did cross a line in a way he hadn't even done before and also that Republicans had to speak out because they believe Trump poses a danger to the party.
