Clearly, Gov. Cuomo was peeved during Wednesday’s debate when GOP challenger Rob Astorino asked him to swear neither he nor his staff had been subpoenaed by the US attorney, who’s probing the decision to shut down a state ethics panel.

The question is “outrageous,” huffed the governor. And though Cuomo defended his handling of the panel, he declined to answer the question that was asked. Understandably, that will lead some voters to wonder if someone on the governor’s staff has indeed been subpoenaed.

On Thursday, The Post gave Cuomo another chance to clear it all up. But an aide, Matt Wing, said, “We are not commenting on the US attorney’s investigation.”

Let’s stipulate: Even if the US attorney, Preet Bharara, has in fact asked Cuomo or his staff for information, it doesn’t mean they are guilty of anything illegal.

Still, Astorino’s question was entirely fair in a race for the state’s highest office.

Recall the facts: the governor set up the panel, called the Moreland Commission, to probe Albany corruption. Soon there were concerns he was influencing the panel’s work. Cuomo first said he had the right to do that, since it was his panel. Later, he said the panel was independent.

Questions arose again when he abruptly pulled the plug on Moreland altogether. His new claim: The panel’s only point was to get ethics legislation passed, and it was.

New Yorkers are about to choose who will hold the state’s highest office. We would have preferred a vigorous debate that focused on the differences between Cuomo’s and Astorino’s plans for the next four years, but the governor didn’t even release his until after the single debate.

If a federal investigation of a politicized ethics panel has become a top political question in this race, it’s not Preet Bharara’s fault or Rob Astorino’s fault. The governor has no one to blame but himself.
