Poll: Do you agree with Sen Corker saying the GOP is in a "cult-like situation?"

well duh, that's just how parties are when they have a good figurehead.

No, that's just how parties are when they have pushed anti-intellectualism for 50 years. *cough* The Republican Party *cough*

Also, studies show that conservatives are much more susceptible to believing in demagogues and false information than liberals.

Ditto. Historical polling of how voters view the economy/trust the government under each president shows considerably more drastic shifts for Republicans. Numerous polls of Republicans under Trump have shown massive shifts in all sorts of views, conveniently to align with Trump. I imagine if you were to rank each person's susceptibility to cults, conservatives would probably ranker higher. They seem to have a soft spot for a strong, domineering leader with authoritarian traits.

Democrats aren't immune from this but their views on issues/confidence in the economy are notably more consistent from one president to the next.
