This year's election could determine which party controls the New York Senate, possibly giving Democrats the keys to state government.
The chamber is now split between the two parties, but Republicans control it thanks to some breakaway Democrats. Democrats say GOP presidential nominee Donald Trump's unpopularity could boost down-ballot Democrats and help retake the Senate.
Polls give Democratic presidential nominee Hillary Clinton the advantage in New York, but news that the FBI is reviewing newly discovered emails possibly related to its earlier investigation of her handling of classified material could upend the race.
Democratic Gov. Andrew Cuomo says Senate control by the party could help him pass stricter ethics and campaign finance laws. Republicans warn one-party rule will lead to higher taxes and a legislative bias favoring New York City.
