I think there may be a large number of Staten Islanders who will now pull the R.
It may well extend beyond that, including lower Manhattan, Queens and Long Island. Here is the county results map from the 2004 presidential campaign (Bush vs Kerry). Blue=Bush; Red=Kerry
The majority of New Yorkers voted for Bush but Kerry won the state with the large metropolises. New York is still considered Obama country but, between the carnage in Queens, the long gas lines, the power outages and the slow response from FEMA, I'm betting that a lot of hungry, unbathed residents who have lost their homes or been displaced by water damage, may very well pull the lever for Romney.
