Depends on how you define "republicans".
Congressional Republicans are 100% deplorable, because they have a very clear duty to reign in the executive. Our system is literally based on the idea that the legislature will do so. Their failure is a national disgrace. Of course, some wishy-washy D's fall into this category as well, though they seem more afraid to cause a blow up rather than robustly endorsing executive overreach.
Individual republican voters, not so sure about that. I am reluctant to criticize anyone for making a bad decision in a two party system that produced a Trump-Clinton choice, though I feel the lesser evil was abundantly clear and has only become more clear as time goes on.
