The only thing that (sometimes) causes the politics of Republicans to change is directly experiencing what their policies support and promote.
See all the Republicans rejecting Trump now when anyone with a brain could see how awful and dangerous he was in the 90s, all those that flipped on LGBTQ+ issues because they had a gay or trans child, those that demonize welfare until their district/state falls on hard times, etc.
I think it’s fair to expect someone who has experienced sexual harassment to be disillusioned by a party that is trying to get a convicted rapist to be President.
