The Daily News reports that Anthony Weiner has filed preliminary papers for a possible mayoral run in 2009.

"I haven't made any firm decisions but what we're doing today is laying the foundation, so that if I decide to run for mayor, I'll win," Weiner, 42, told the Daily News... Asked yesterday how serious he is about running again for mayor, Weiner replied, "Many of the same things that I talked about when I ran for mayor in 2005 continue to keep me up at night." Other potential Democratic rivals include City Controller William Thompson, City Council Speaker Christine Quinn, Bronx Borough President Adolfo Carrión and Brooklyn Borough President Marty Markowitz. Councilman Tony Avella (D-Queens), a self-described "long shot," is the only officially announced candidate for mayor in 2009. Mayor Bloomberg must step down on Dec. 31, 2009, because of term limits.

Of course, our very own Liza has said that she'd get in the race in the event of a Betsy Gotbaum candidacy, with the express intent of heaping ridcule on that poor, befuddled creature.
