That's been the issue all along. The politicians at the top are all too eager to let the wingers have their field day. Notably, they don't have to push or endorse as long as they express their support. "Surround them, push them out", "Bring a gun to a knife fight", and the trained seals applaud and rush to explain they didn't REALLY mean for people to get violent (nudge nudge, wink, wink).
It would have been nice to see the guy at the top in the last admin not refer to those who didn't vote for him as enemies, threats, etc. but one remembers ranting and raving, waving fists against a bloodred background.
