Sorry it took so long to respond to this. So, the bolded seems pretty concerning (if I'm interpreting this correctly). Are you saying his greatest value is being able to vote for Republican policies because Warnock won't and all the other personal stuff is... irrelevant? Mostly less relevant?
I guess it's about where we draw the line. I realize much of his well-documented personal issues happened 10+ years ago, but some of them have not. He's currently being sued over an alleged $200,000 debt and it was only two years ago that he talked about some nonsensical COVID mist that kills the disease in your body. His past is littered with some whack-a-doodle stuff.
As far as his mental disorder, I don't think a guy should be punished eternally for something like that, however it is absolutely relevant for someone who wants to hold public office... and by and large, most people don't get 'cured' of that disease. They have to just treat and manage it. Based on past and more current evidence, he's clearly prone to instability... both financially and personally.
Much like the California democrat who is allegedly battling memory issues right now, we need the right people to represent us. Walker isn't and shouldn't be that guy IMO.
