No they don't.

Trump voters don't regret anything regardless of age. The bulk of them get entirely different news then we do. If any at all except thier local news. They don't know what rest of the country looks like. And the ones that do don't care and itch to avenge their great grandpappies plantation.

It's a wonderful cocktail of ignorance and malice. And the only way to get them to regret anything or change thier mind is death.

Mass, uncontrolled death tolls, when they can't get medical care, they have no one to sell thier crops to, they can't afford basic nessesities...

That's the only thing. And that's just for the ignorant. The hateful just have to fear being hateful again.
