The GOP has been hollowed out to the point that they're incapable of admitting this to themselves and participating in corrective action. The courts alone aren't sufficient. And because our elections are held on a clockwork cadence there's not much the citizenry can do at this point.
Which is why I'm worried things are going to turn violent. When normal channels fail, people who feel like they have been pressed against the wall will act out in other ways. And a lot of people are in the process of having their livelihoods ruined.
