In the off chance you have been living under a rock and came up only to read the TC, NB today is Election Day. (This message above, caught by JPL, was on One World Trade starting this weekend.) You can find your polling place here. Polls are open from 6a to 9p.
Just a little background: most of us in Tribeca are in Assembly District 66; the Civic Center and Chinatown are in AD 65; Battery Park City, Fidi and the north side of Staten Island are in AD 61. Even within the Tribeca section of AD 66, there are 10 election districts and three polling sites, so be sure to look yours up.
There is also a wait-time map here.
The sample ballot is below, but you can also check a pdf of them when you look up your polling site.
And there is some more info here on the ballot and propositions.
