YAPHANK - Many voters on Long Island aren't sure where to cast their ballot on Election Day tomorrow after Superstorm Sandy knocked out power to dozens of polling places. Nassau election officials say Sandy disrupted as many as 70 polling sites. Polling locations in hard-hit areas like Long Beach, Oceanside, East Rockaway and Island Park are being consolidated into a handful of larger polling places. Suffolk polling sites are dealing with their own set of challenges: about eight polling places are being relocated, and dozens more will be powered by generators. Both counties recommend that voters double-check that their usual polling place will be open before traveling there. Election officials warn that it won't be the most optimal voting situation, but say that Long Islanders will be able to cast their ballots tomorrow.Gov. Andrew Cuomo announced this evening that he will allow affidavit voting for Sandy victims. Displaced voters who sign an affidavit stating they're registered to vote will be permitted to cast their ballots for state and federal races at any open polling site tomorrow.Cuomo to allow affidavit ballots for Sandy victimsInformation for Voting after Sandy:Nassau and Suffolk Polling Places Nassau Votes Suffolk Votes U.S. Attorney's Office Fielding Election Complaints
