Gov. Andrew Cuomo pretended his line went dead during a radio interview when asked about supporting a possible presidential run by Mayor Bill de Blasio.

The governor went silent for about 15 seconds and made a muffling sound, as if static on his phone line had interrupted his interview on WAMC radio.

“I’m sorry, doctor, I missed your last question,” Cuomo told interviewer Alan Chartock.

“Do you have the chutzpah to restate it?”

When Chartok did just that, Cuomo said it was too early to be talking presidential endorsements.

“I’m not prepared to make any endorsements. A fellow New Yorker, Sen. Gillibrand, is also running,” the governor said.

“But he hasn’t announced. If and when he announces, I’ll have a comment at that time.”

De Blasio has been trying to position himself as a 2020 contender.

Cuomo was kinder to former Mayor Michael Bloomberg, who is taken a lot more seriously as a possible presidential candidate.

“He’s a credible fellow, no doubt,” Cuomo said.

“He has credibility of being a businessman and he ran the city of New York.”

De Blasio has run the city for five years.
