Gustavo Rivera defeated Councilman Fernando Cabrera in the Democratic primary for the New York State Senate's 33rd District.
Rivera, the incumbent candidate, claimed 60 percent of the votes. He first went into office in Jan. 2011.
If he wins the general election, he will serve his third term for the district.
Rivera's campaign manager told News 12 that he had visited several senior centers in the district, attended an anti-gun violence event, and knocked on doors of constituents to shake their hands and ask them to come out and vote.
