How does affect things downballot?
It's tough to tell. Shapiro has a history of having unique crossover appeal (see: 2016, 2020) so it's possible that he doesn't do much to drag downballot Dems across the finish line, but I wonder how much of an impact he could have for people like Cartwright, Wild, and Deluzio. Even Ehasz and Daniels in PA-01 and PA-10 respectively could benefit, but I doubt enough to win.
The legislative ballot is what will be most interesting. Luckily this year we have much better maps so interesting to see if Dems can actually win one of the chambers.
Also, the LV model is +10, so added that to the OP. Makes more sense since clearly some of those undecided or 'someone else' get allocated to Mastriano.
