Island-wide, voters are casting ballots in 118 races.

There are also five proposals on the ballot all across New York state this year.

• Proposal 1 involves redistricting of legislative and congressional district lines. It would count any resident of a district as a voter even if they are not a U.S. citizen.

• Proposal 2 could impact where and when new developments related to clean air and clean water take place.

• Proposal 3 would allow voters to register less than 10 days before an election.

• Proposal 4 would eliminate the requirement that a voter provide a reason for voting by absentee ballot.

• Proposal 5 would increase the New York City Civil Court's jurisdiction by allowing it to hear and decide claims for up to $50,000 instead of the current limit of $25,000. Some believe this could alleviate the caseload of the state Supreme Court.
