Dick Parsons for New York City mayor? A few weeks ago, I picked out an interesting tidbit in a story on why Parsons should be fired: Gramercy Capital Management's Joan Lappin dribbled the tantalizing rumor that the Time Warner CEO was considering a run for mayor when Michael Bloomberg's term is up in 2009.

Today's New York Magazine says "it's all but official." Parsons will run, with some insiders even saying he'll hand over the CEO position to Bewkes (Lappin said this, too) before his current contract ends in 2008. Naturally Parsons has said he'll fulfill his contract, but not opined on the mayoral run.

Frank Barnako of MarketWatch says this must be why Carl Icahn is buying up shares of Time Warner, while DealBreaker.com says Parsons entrance into the race "is not entirely unwelcome" and hints that the I-banking elite might vote for him. Would you?
