Former Rep. Anthony Weiner, D-N.Y., spent over $100,000 on polling and research this month, reports the Wall Street Journal, generating speculation that the former congressman, who resigned in 2011 after revelations that he had sent lewd photos to women over the internet, could be preparing to mount a political comeback.

Prior to his fall from grace, Weiner had been preparing for a New York City mayoral campaign. The $100,000 came out of his city campaign account, which still has $4.3 million remaining, and was reflected on a report filed on Friday with New York City election officials.

Weiner declined to comment on the spending, telling the Wall Street Journal that he had "nothing to report beyond what I reported."

In January, the New York Daily News reported that Weiner's name was among five prospective mayoral candidates voters were asked about in an survey. It is not clear whether the survey and the more recent polling expenditures are connected in any way.

Several of Weiner's potential rivals in the mayoral race greeted the speculation about a comeback with nonchalance, according to WCBS in New York.

"I think Anthony should be there. I think he should run. Just stop texting," said City Comptroller John Liu.

"I think we've got one of the most crowded mayoral races we've ever had," added Public Advocate Bill de Blasio, "but everyone makes their own choice.

City Council Speaker Christine Quinn, considered an early frontrunner for the Democratic nod, said, "I think Anthony's future is up to Anthony, but I wish him nothing but the best, he and his family."
