ALBANY, N.Y. (AP) — Four Republican candidates for New York governor pledged to undo years of one-party rule and focus on battling crime if elected to office during a televised debate Monday night.

The field includes U.S. Rep. Lee Zeldin, former Westchester County Executive Rob Astorino, businessman Harry Wilson and Andrew Giuliani, the son of New York City’s former mayor. It’s an uphill battle for Republicans vying for the governor’s office in New York, where registered Democrats outnumber registered Republicans by more than 2 to 1.

Giuliani, a former adviser to former President Donald Trump, said Sunday he was barred from participating in-person in the Monday primary debate because he has refused to submit proof he’s been vaccinated against COVID-19.
