The thing about the far right is it tends to get out of control and ends up eating its own. Politicians give it momentum and by the time they want to put the brakes on, it's no longer theirs to stop.
It’s the political extremism ouroboros - any political ideology that is based upon hate inevitably ends up eating itself as they need to keep inventing things to hate and eventually turn inwards. I love to see it.
I'm pretty sure this is exactly it. If Trump were killing it to the point they knew no matter what he would win she more than likely wouldn't have said anything.
