The repeated disillusionment of conservatives with the GOP, then the Tea Party, now Ryan and the Freedom Caucus (and I suspect if he were ever elected, Trump) reminds me of something.
I recently just watched Show Me A Hero and how Yonkers mayoral politics in the late 80s/early 90s was basically a revolving door of candidates promising to oppose expansion of public housing into middle class suburban areas, even though the candidates often knew full well they wouldn't be able to do shit to stop it because of the order of a Federal judge.
But each time they'd get in, hit reality, the residents would continue to flip out, and someone else would promise they'd be the one to truly offer change and get in on anti incumbent sentiment. Rinse and repeat.
It's a testament to just how clueless people are on how their government works, even on the local level.
