Trump has a very long history of using this kind of thing to say what the campaign is thinking about doing.
If you want to stop that kind of fascist outcome, about the only real option is to make sure Biden gets reelected and has a Democratic congress to help him.
That means three things:
- Double-check your voter registration. Turned 18? Register. Moved? Register. Changed name? Register. Live in a state where Republicans might have purged your registration? Check your registration
- Volunteer. That means in-person if you can. Phone bank if you can’t.
- Kick in what money you can. To the Biden campaign and to a close house or close senate race.
When a campaign hires staffers like Stephen Miller, and the candidate has said neo-nazis and white supremacists are fine people, that right there is likely the reason.
