Rep. Lee Zeldin (R-NY) is the frontrunner with a commanding lead over his challengers in New York’s Republican gubernatorial primary, according to a new poll.

An Emerson College Poll found that 34 percent of very likely Republican primary voters support Zeldin for New York governor. Zeldin’s 34 percent is a double-digit lead over the next closest challenger, Rob Astorino, who earned 16 percent of Republicans’ support.

Trailing behind Zeldin and Astorino are Harry Wilson and Andrew Giuliani, who earned 15 and 13 percent support, respectively.

The poll found that 22 percent of Republican voters remain undecided ahead of New York’s gubernatorial primary on June 28. However, when undecided voters were asked who they were leaning toward, Zeldin’s lead increased to 40 percent.
