There are people who won't talk to anyone from the political religion opposite to theirs. Both sides call each other Nazis. And they'll vote for a candidate from their party even if the candidate would have to rule without regaining consciousness before they'd consider the other party. I think that's a pretty extreme level of brainwashing.

Yes, but you'll find rabid rabble rousers in spectator sports as well. While this may say something about the polarization of the parties, it says a bit more about individual and group psychology. And doesn't say much at all about the organization of power in the US.
