DeB run at gov would likely spell ‘de’feat

If he’s harboring any thoughts of challenging Gov. Cuomo next year, Mayor de Blasio would be well advised to shelve them, according to a poll released on Friday.

The Quinnipiac University poll found that even in the mayor’s stronghold of New York City, Cuomo would clobber him in a 2018 Democratic gubernatorial primary by grabbing 60 percent of the vote to his 31 percent.

The results were so lopsided that even Democrats who consider themselves “very liberal” were split, with 48 percent backing the mayor and 46 percent going with the more moderate governor.

Still, all public polls make de Blasio a heavy favorite to win a second mayoral term in November.

His repeated run-ins with Cuomo, as well as his extensive travels, have raised questions about whether the mayor has political aspirations beyond City Hall.

By his own words, he’s sticking around through 2021 if re-elected.

“I’m running for one thing and one thing only — mayor of New York City,” de Blasio declared during a Democratic-primary debate last month. “I will serve for the full four years.”

Most voters think the city is headed in the right direction, according to the poll, but still harbor reservations about their mayor.

In a stinging slap, city voters by a 35 to 27 percent margin said their political views align more closely with the governor’s than with de Blasio’s.

The relationship between the governor and the mayor is so tense that Cuomo didn’t get around to endorsing his fellow Democrat until after the Septem- ber Democratic primary — and then only grudgingly.

“The mayor won the Democratic primary. I am a Democrat. I support Democrats and I will support Mayor de Blasio in the general,” Cuomo said on WNYC radio on Sept. 18.

Voters take a dim view of their never-ending feud, with 52 percent saying it is hurting the city.

But, once again, more of them side with Cuomo (43 percent) than de Blasio (32 percent).

Nearly half — 47 percent — think the dueling politicians have “honest disagreements,” while 35 percent say the feud is “personal.”

There was better news for the mayor in a Marist College poll released Thursday, which showed him breezing to re-election with 58 percent of the vote.

His closest rival, GOP challenger Nicole Malliotakis, was far behind with 16 percent, while independent Bo Dietl and Reform party candidate Sal Albanese each got 5 percent and independent Michael Tolkin 1 percent.
