Why would anyone reveal how they voted?
We have a curtain on the voting booth for a reason.
Since New York went 59% for Hillary, her vote didn't matter.
However, "Chuck E Cheese" Schumer is probably aware of how large a check Hilary Califano cut for Trump. (Of course, money wasn't the Democrats' main problem, since Clinton outspent Trump by a roughly 2:1 margin.)
As Mark Twain said, "Denial ain't just a river in Egypt".
Schumer is between a rock and a hard place with the Gorsuch filibuster. If he filibusters, Mitch McConnell will go nuclear, and when the next liberal SC justice retires, a conservative will be a shoo-in. If Schumer doesn't filibuster, the moonbats will be calling for his head, and they might get it.
