Yes, that is a shit thing to do and to publicize it just to draw attention to yourself. But, that's Willard's game, just what he does. Conventional wisdom says no matter who wins this year he'll try again in 2024.
The good news is that if he votes in Utah then that state isn't going blue anytime soon, so not too much damage done. Likewise, we've seen how much pull he has with dems and the undecided (zilch). As I said, as long as he doesn't bullocks the ACB confirmation then he's just an insect. I hope the people of Utah will figure him out soon and get a real Republican as their senator.
