I agree with this analysis and is why I'm a "Republican" no more.
Over and over "conservatives" prostitute themselves defending the indefensible lowering what was conservatism further and further until it is no different than the deranged left. Character and principle no longer matter. Only "truth" to power, the rawer and cruder the better.
Schwarzenegger was the final straw in California and Trump will likely be the final straw in the country for conservatism.
In both elections there was the option for a renewal of conservative principle, to change course and improve things, but coarse celebrity won the day instead.
For short term stick it to the establishment populism we traded our long term future.
