Years ago I interviewed a Republican Party bigwig in Florida who screeched about how Europe was a "socialist hellhole" with every small business being crushed by taxes and regulation (and of course that Obama was going to do the same in the U.S.). Then, speech over, he casually mentioned that he went to Europe all the time, loved it, and made lots of money there.
It's always been performative. But, just like immigrant-bashing, eventually the drones start taking the speechmakers at their word.
