I think the thing I like least is the climate change denialism, of course. Here's a recent interview:
CRUZ: OK, you are incorrect, actually. The scientific evidence doesn't support global warming. For the last 18 years, the satellite data - we have satellites that monitor the atmosphere. The satellites that actually measure the temperature showed no significant warming whatsoever.
INSKEEP: I'll just note that NASA analyzes that same data differently. But we can go on.
You bet NASA analyzes that data differently--they find there's no significant proof there was a hiatus at all. The interview is a masterpiece of framing--the climate scientists are a cult, and only the skeptics are being honest. This is probably why he put a talk-radio guy on to testify to the Senate about climate change. It's staggeringly dishonest, but for Cruz, what else is new? This is a guy who will even repeat a lie about prayer. He's the worst.
CRUZ: But no, they don't. You can go and look at the data. And by the way, this hearing - we have a number of scientists who are testifying about the data. But here's the key point. Climate change is the perfect pseudoscientific theory for a big government politician who wants more power. Why? Because it is a theory that can never be disproven.
