The republicans have already indicated they are done with democracy. Why would they care if the voters don’t like it? They’ll just change the electors to whoever picks what they want
They believe they can. They tried last election and they'll try again as they had zero fucking consequences. If you think they wont try you are either one of them or have your head in the sand.
Edit: It was also frequently stated that "no, they wont" when people were worried about the conservatives overturning roe v wade, but here we are!
