With the EV registration looking the way it is, there shouldn't be an unexpected wave. The results will be about persuasion in specific districts so you can't entirely dismiss the possibility of Democrats flipping all of the South Jersey marginal seats or the GOP tying a chamber.
Given the EV and how it looks compared to the past, and how there's still pretty minimal Indy-involvement, the latter seems much more unlikely vs the former.
I agree, but there is an ancestral Dem registration factor in South Jersey where it's closer than the EV indicates. The winds are blowing so strongly in the GOP's favor that even Norcross obsessing over Durr might not be enough. Ciattarelli won that district by 16 points and that's a lot to make up.
Do you have EV data for South Jersey in 2021? That might give a better clue about where things are heading.
