Mike Bloomberg may be feeling a bit of buyer’s remorse: As Bernie Sanders surges in the polls, the billionaire candidate is suddenly not so sure about his earlier pledge to support the eventual Democratic nominee, according to a New York magazine profile.

During a campaign stop in Houston on Feb. 27, Bloomberg told a voter he might not support a nominee who rejected his largesse.

“What do you mean, I’m going to send a check to somebody and they’re not going to cash the check?” said the ex-NYC mayor. “I think I wouldn’t bother to send the check.”

Sanders frequently boasts that he is not supported by any billionaires and his top brass have explicitly said they’d refuse future help from Bloomberg’s vaunted campaign operation.

“It’s a hard no,” top campaign adviser Jeff Weaver told NBC after the Democratic debate on Tuesday. “Bernie has said he’s going to fund his presidential campaign with small-dollar contributions, and I think we can do that. I think we can raise over a billion dollars in small-dollar contributions.”

In January, amid mounting concerns from Democratic Party bosses, Bloomberg pledged to support the eventual Democratic nominee if his own effort came up short.

“Mike Bloomberg is either going to be the nominee or the most important person supporting the Democratic nominee for president,” campaign manager Kevin Sheekey said at the time.

The sudden reassessment from Bloomberg comes as Sanders has romped to victory in early states, while his own campaign has stalled after two lackluster debate performances.

Team Bloomberg did not immediately respond to a request for comment from The Post, but insisted to New York magazine that Bloomberg would still fund efforts to defeat Trump whether or not Sanders wanted him by funding an outside anti-Trump super-PAC.
