Cuomo won the 11th by 15, while Grimm won the 11th by 13. Look at that ballot splitting.
That really just goes to show how horrible Astorino is.
No, Astorino did outstanding upstate. There was a clear division between upstate and the NYC area in the governors race. Staten Island is usually Republican leaning, but I don't really know why Cuomo won it by so much.
I'll give him credit for outperforming Palladino, but someone from Westchester really ought to have cleaned up in Staten Island. It's just extraordinarily difficult to win statewide when SI/LI and upstate are often divided. I should add that winning Suffolk's not a bad accomplishment either. Probably just expecting too much due to the national wave.
