Both of these things can be true:
1. Oz has largely consolidated the base and mostly succeeded in righting the ship.
2. Righting the ship has made the race more competitive but not solved the GOP's main problem in PA: Oz's personal favorability ratings remain low enough that he will struggle where a generic R would have had a much easier time: actually winning over the lion's share of undecideds and genuinely independent/persuadable voters.
I know I sound like a broken record here, but Masters's unfavorability #s strike me as a lot 'softer' than Oz's, so again — it seems foolish to rule out AZ being the tipping-point race in the Senate instead of PA (although both are winnable for Republicans, at least in theory).
The problem with that is that (1) GOP has largely abandoned AZ for some reason if you look at spending (and big spending advantages in final weeks do matter), whereas Oz is closer to parity, and (2) Kelly is a much better candidate than Fetterman when it comes to winning over Biden Republicans.
