The Board of Elections site does not have this information posted as far as I can tell but I was informed that Primary Day for all Congressional races in New York is June 28, 2016. The Gotham Gazette has a piece about voting days this year and next, “Many Voting Opportunities for New Yorkers in 2015 and 2016”. I missed that earlier in the year.
Voters in New York will decide on their party’s candidates for all Congressional races in the state on June 28, 2016. This includes the primaries for all 27 of New York’s members of the House of Representatives. Democratic Senator Chuck Schumer will also be running for reelection on this day.
The Board of Elections site does remind us that :
