By chance, I happened to mention exactly this to a friend of mine last night:
Are you aware how much the constant threat of violence, principally from MAGA sources, is now warping American politics? If you wonder why so few people in red America seem to stand up directly against the MAGA movement, are you aware of the price they might pay if they did?
....Judge Tanya Chutkan, who is overseeing Trump’s federal Jan. 6 trial, has been swatted, as has the special counsel Jack Smith.... The Colorado Supreme Court likewise endured terrible threats after it ruled that Trump was disqualified from the ballot.... Mitt Romney faces so many threats that he spends $5,000 per day on security to protect his family. After Jan. 6, the former Republican congressman Peter Meijer said that at least one colleague voted not to certify the election out of fear for the safety of their family.... In 2021, Reuters published a horrifying and comprehensive report detailing the persistent threats against local election workers.
It's telling that this comes from David French, who is sensitive to it—and willing to talk about it—because he and his family have been persistently under threat thanks to his anti-MAGA stand.
So far, these threats have been generally hollow. They come from angry Trump supporters who want to intimidate their opponents, not kill them. But that's how it's started in other times and places too, and there's not much question that it's inspired by Donald Trump himself. He approves the violence of January 6. He constantly threatens to throw Joe Biden in jail when he becomes president. He's going to sweep up and deport every illegal immigrant in the country. His top generals deserve to be killed for opposing him. The language of anger and violence is not even below the surface of everything Trump says. It's right out in the open.
