With the election less than a month away, Gov. Andrew Cuomo still hasn’t agreed to a single debate with Republican challenger Marc Molinaro.

Critics — who include Democrats — say that’s not how democracy should operate.

“The opponent is not Donald Trump. The opponent in Marc Molinaro,” said City Councilman Ruben Diaz Sr (D-Bronx). “Stop hiding! Show the people why you deserve a third term.”

Diaz suggested a one-on-one debate without the minor party candidates — and preferably in the The Bronx.

“Do it at Hostos Community College. Show you care about minorities,” Diaz said.

Fearing a backlash from the left, Cuomo granted one debate to Democratic rival Cynthia Nixon before the Sept. 13 primary.

“Cuomo needs to make the argument to the voters on why he’s the best person to govern New York State,” said John Kaehny, director of the government watchdog group Reinvent Albany.

He also called for more than one face-off.

“There shouldn’t be just one debate. There should be a bunch of them,” Kaehny said.

The other candidates in the race are: Howie Hawkins of the Green Party; Larry Sharpe of the Libertarian Party and Stephanie Miner, the former Syracuse mayor and co-chairwoman of the state Democratic Party, who is running as an independent.

Cuomo participated in just one hour-long debate in 2014 — but it included the candidates of the Green and Libertarian Parties, leaving little TV time for Republican Rob Astorino.
