Yeah. As I mentioned before, it might help Fetterman similar to how Tammy Baldwin arguably pulled Evers over the line.
I think it’s usually thought that the governor race does the pulling. It holds the top position on the ballot, so it informs the subsequent choices. Shapiro might pull Fetterman over the line, but I don’t think Baldwin pulled Evers over the line. Walker was very decisive in a neutral state in a wave year. I think his performance was actually quite good in retrospect.
Either way, the gap between Fetterman and Shapiro will be overestimated by the pols. Whether that means Shapiro does worse or Fetterman does better will determine the Senate race.
Given recent history, I wouldn't be surprised if it means Shapiro does worse. By "worse", that would mean he would win by "only" 6% or so, while Fetterman defeats Oz by 2% or so.
Yes, there's a couple different scenarios here:
1. Undecideds break against Mastriano as he gets triaged, but toward Republicans in general (think of PA-GOV 2014): Shapiro +12, Oz+2, Republicans hold the state legislature, etc.
2. Polling is understating candidates with the most working class appeal (think of 2016 and 2012 together): Shapiro +5, Fetterman +3, US House and state legislative Republicans overperform expectations
3. Polling is understating Republicans across the board, possibly dramatically (think of 2020 or VA 2013): Shapiro +2, Oz +5, big Republican US House and state legislative gains
