[insert usual caveats about polling here especially so early in her campaign]
Whatever foothold Trump was starting to get in Minnesota has evaporated. Faux has him down I believe 6 points here to Harris and the local ABC affiliate (a rather conservative station) has him down 10 to her.
Also, Faux has every swing state tied or around a 1 point.
Now again usual caveats in play here and of course she is getting a nice bump from stealing all of the air out of the room for almost a week so far but assuming Trump has any politicians working for him that actually know what they are sweating. I mean the dude got shot and he had his convention and he has remained flat. His Hillary like obsession with "expanding the map" is not going well at all. And if you go back to a post I made yesterday some of the places where vote.org is showing increases in registration are places like Michigan, NC, and Pennsylvania. If they aren't in Pennsyltucky he has issues. And if Harris takes another week or more to find a running mate she is going to continue to take up a lot of the press...except the stuff Trump definitely doesn't want in the cycle. (i.e. JD Vance and Project 2025)
Harris needs to take her time with this both because it will strangle his coverage and the wrong pick will kill momentum. Personally I think she needs to avoid Shapiro like the plague because of Israel. If Kelly can't fix his union issue I think you need to keep him away as well. (unless the unions, especially UAW approve) Beshear, Secretary Pete and Walz would be my short list but I am a nobody in the suburbs of Minneapolis so my opinion aint worth much.
