Like, if you remember what Walz was like when he first started, he was really going in on the "weird" label, making JD Vance couch jokes, and was really making himself visible. And people really liked him.
Then we saw reports of the campaign having ex-Hillary staffers saying they want to stop using the "weird" label, because it's too polarizing (the one attack that was really getting under their skin).
Then afterwards, Tim Walz was barely visible and mostly milquetoast. At the VP debate, he was uninteresting.
Early on, the Republicans were trying to attack him, but the only attacks they could come up with are stuff that say more about themselves than him (Tampon Tim, the whole "he's weird because he hugs his children). But then they didn't even need to attack him.
The Democrats absolutely hate winning, part X.
I think a good point was made on Hasan's stream during election night: what was the point of picking Walz, if you were then going to force him to do right wing messaging that he wouldn't deliver convincingly? For a second there, it almost seemed like the campaign was about to pivot into a more progressive messaging campaign... but then they just ran as if they had Shapiro as VP.
