Voters heading to the polls for next month's presidential primary will also be picking their choice on the same day to fill Dean Skelos' seat.
Voters will cast their votes for the primaries and the state Senate seat on April 19.
Democratic state Assemblyman Todd Kaminsky is running for Skelos' seat and is focusing on ending corruption in Albany. His Republican opponent, attorney Chris McGrath, says the big issue is ensuring Long Islanders aren't taken advantage of.
Political experts say turnout for New York's presidential primaries could have an impact on the state Senate race. Hofstra political analyst Larry Levy says polarization over Donald Trump leaves the state Senate candidates in a tough spot.
"It's a tricky situation for Todd Kaminsky," Levy says. "He risks alienating some independents that have shown a propensity to support Trump... Chris McGrath faces the same problem from the other side. If he embraces Trump, he risks alienating other Republicans. If he doesn't, he risks alienating Trump supporters."
In many of the early primary and caucus states, Republican turnout has far exceeded Democratic voter turnout. That has some local members of the GOP thinking Trump's presence can only help McGrath.
Nassau Republican Committee Chairman Joe Mondello says he believes voters who are drawn to the polls to support Trump will also vote for McGrath.
News 12 reached out to the Kaminsky campaign, but a spokesperson declined to comment.
