Walker literally came out and said he's "not that smart" recently. It's very obvious and believable. Somewhere in that concussion addled brain even he knows he's a idiot. You can barely understand him when he talks, and he either rambles in ways that don't make sense or jumps to weird non sequiturs. He will jump to some random Republican talking point like he's some weird parrot when it's not even the point of conversation, and then it's obvious he doesn't even understand those. I wouldn't trust his character or his competence to be my grocery store shelf stocker let alone senator. His beliefs are a sham. He doesn't care about anybody but himself. Oh, and it's pretty obvious by now that he's a scummy human. The guy will also fucking sell you out in an instant for cash and that sweet sweet rich donor money.
...then again...all that makes him the perfect Republican doesn't it?
Either the fake Christians will gobble up any half-assed apology from him as rationalization or tribalism will make Republicans go with him no matter how insane it actually is becuse of Jesus, or guns, they like to lick corporate boot, or because they think the gays and trans are going to jump out of the bushes and get cooties on them.
Even his potential Republican colleges wouldn't like him as much want him because he's stupid enough to be their useful stooge and puppet that will do whatever he's told.
Whatever faults Warnock might have he's lightyears better than Walker. The gulf in intelligence is competence is gigantic, and Warnock might actually give a shit about your wellbeing
