I agree with everything you’ve said, the optics and the “feels” are at an all time high.
That said, a lot of reporting is saying that the choice of VP doesn’t have a significant impact on election day.
IDK how that can really be true though. For the next several months Walz will be shaping the public’s opinion of Kamala. Obviously on election day people will vote for Kamala or Trump, but Walz can convince people to vote for Kamala.
