Publicly, no, not many GOP politicians are going to stand up to bannon. If they come out for, too hard, people are going to remember and -- as noted earlier -- bannon is the sort of critter that even a lot of the republican base isn't entirely comfortable acknowledging. If they denounce, well, you just affronted someone that's now close to the oval office and has the support of a smaller but louder (and notably more likely to shoot you, for what that's worth) chunk of your base, too. There's basically not really a win condition for closer to center (if in nothing but demeanor) GOP politicians when it comes to folks like bannon, particularly when they're in a position with much power. So they're probably going to stay pretty mellow on that front, if I had to take a guess.
Now, the GOP being weaselly little shits they are, there's all sorts of things that could turn that guess on its head. Trump screws up enough and public opinion turns on him hard, you're more likely to see some noise towards the alt-right & co shitheels. It actually turns out he's not a disaster and somehow or another what he's been saying he wants to do works, or he manages to 180 on it hard enough without the base revolting on him, and sentiment actually starts rising, then you're probably going to see politicians warm up to the guys in question. Somewhere in between, where things go as expected but folks aren't as quick to get pissed about it, things'll stay about the same. Tbh, so far as the US right goes, that second one is probably our worst outcome. Further normalization of that sort of conservative and more expressing of their voice and messages is a distinct loss for just about anyone approaching sane in this country.
