Anthony Weiner, the disgraced ex-US congressman forced to resign after tweeting lewd photos of himself to women, on Monday reopened a Twitter account in an apparent political comeback drive.

Weiner, 48, who said earlier this month he was weighing a comeback with a run for mayor of New York City, opened the account @anthonyweiner -- which listed no "live" tweets, but retweeted some policy papers.

Weiner dipped his toe back into the Twitterverse by retweeting a document "64 ideas to keep new york the capital of the middle class," and another on Earth Day, but quickly lured more than 5,000 followers.

Weiner was once seen as a frontrunner to replace billionaire Michael Bloomberg in November elections to the Big Apple's City Hall.

But the Democrat's hard-charging political career in the US House of Representatives imploded in 2011 with the X-rated Twitter scandal.

Now he has told The New York Times he could get back into politics and commissioned a poll to know if New Yorkers would give him another chance.

"I don't have this burning, overriding desire to go out and run for office," he said. "But I do recognize, to some degree, it's now or maybe never for me, in terms of running for something."

"Am I still the same person who I thought would make a good mayor?" he asked.

Weiner -- who is married to Huma Abedin, Hillary Clinton's top aide during her time as secretary of state -- initially claimed his Twitter account had been hacked and he had not sent the pictures.

He finally admitted the truth and also said that for several years he'd been in racy exchanges via text message and Twitter with women that he never met.

The already crowded field in the New York mayoral race is led by current City Council Speaker Christine Quinn, according to polls. The Democrat would be the city's first female mayor.
