Doesn’t matter if it’s 100% of them or 0% of them, that’s the mathematical reality of the NY electorate.
If you want to win statewide as a Republican you have to get a significant number of register democrats to vote for you.. or have a D candidate running against you that is so bad democrats stay home.
The fact this democrat is polling at 55% actually shows how weak she is, to only be at 55% means she either not carrying a sizable number of democrats or literally everyone who is not a democrat is voting against her (highly unlikely)
That’s why any Democrat-led city is hopeless. It takes someone like a Giuliani to clean up a place like NYC. Dinkins let it become so nasty that even Dems were clamoring for law and order. I think Adams is close.
