Vote, Baby, Vote (Green)
If you live in NYC, the only reason I can think to actually trudge over to some crappy middle school and vote is that the Green Party needs 50,000 gubernatorial votes (Malachy McCourt) for the party to automatically get a line on the ballot the next four years. It's going to be close. If they don't get those 50,000 votes, it puts a big burden on them to spend money they don't have gathering signatures in local elections. The Greens actually have had some success in local offices in New York State (cf New Paltz), so it seems worth pursuing.
Also, I'm joining the Room 8 drive to write in Adam Green for Comptroller (including this handy guide to the process of writing in candidates).
In a nutshell: Vote Green, then vote Green. Baby.
