Bat guano crazy left is now standard-issue for Democratic politicians.
One thing that surprised me a little bit is how much their ads (negative or positive) centered around supporting Biden. I think that dropped off a bit after the debatcle (debate/debacle - see what I did there?), but not by much. Their ads were also hyper-focused on abortion (which is now basically illegal in Missouri).
The attack ads against Bush also accused her of being a non-entity as far as any accomplishments while in office.
