Former state Sen. Terry Gipson has taken another step toward running for governor, forming a campaign committee to explore a statewide run next year, according to a filing posted Friday at the state Board of Elections.

Gipson, a Democrat, served one two-year term in the state Senate, representing the Poughkeepsie area. He lost his seat in 2014 to Republican Sen. Sue Serino and failed to win the Hudson Valley district back in a 2016 rematch.

Gipson has previously expressed an interest in running a primary challenge to incumbent Democratic Gov. Andrew Cuomo, who is seeking a third term next year. He would likely run to Cuomo’s left on a variety of issues, including education spending.

Other potential primary challenges to the governor next year include Syracuse Mayor Stephanie Miner and New York City Councilman Jumaane Williams.

Cuomo defeated Fordham Law school professor Zephyr Teachout in a 2014 Democratic primary.

A Siena College poll this week showed Cuomo with a 69 percent favorable rating among liberals and 68 percent among Democrats. Sixty-four percent of Democrats and 64 percent of liberals are willing to re-elect Cuomo next year, the poll found.
