From the Village Voice:
"Just because you're displaced doesn't mean you're disenfranchised."
It's evident that, a week after Sandy, thousands of New Yorkers are still reeling from her aftermath, many of them without homes, power or, particularly on Election Day, the ability to get anywhere near their assigned polling station. Although the plight of the displaced might be prioritized over casting a ballot, the threat of missing hundreds, if not thousands, of votes has become a major issue here, in New Jersey and in the rest of the Sandy-stricken states.
For this reason, Governor Cuomo, in a statement that included the line above, declared a measure that would allow all New Yorkers to vote from anywhere in the state. But, there's a stipulation: you can only vote for the President and Senate from a different location; you cannot vote for your local elections if you're not in your own district.
Today, any displaced voter in New York can walk into a polling station, sign an affidavit and choose the next President and Senator from New York. According to Cuomo, this was an "extraordinary" but necessary compromise: "We want everyone to vote... But in the local races, if you vote in a different Assembly district, a different Senate district, your vote will not count in that district. That is the downside to the system."
So, if you want your vote to actually mean something, find a polling site in your assembly district.
