Not saying there isn't a new horror right around the corner, but Hatch / Sweetcell are 100% right...there isn't anyone that takes over that movement when he's dead. I don't think that means it disappears overnight, but who can pick that up? His swagless kids? DeSantis? Be serious...you can say a lot about Trump and be right 999% of the time, but he does have a certain something that riles up the swine, and none of these other pretends comes close. They're riding his coattails.
But as for "beating him at the ballot box", unless it's a bloodbath, another close loss isn't going to move the needle. They already think the last election was stolen! What's going to make this time any different?
