Ousted Rep. Alan Grayson (D-Fla.) laid into President Obama and his fellow Democrats in an exit interview with The New York Times, leaving open the possibility of another run for Congress in 2012.

The outspoken liberal, who lost his bid for reelection by a wide margin to Republican Dan Webster, told the paper that Democrats are largely to blame for the loss of the party's majority in Congress and that the president's shifting position on George W. Bush-era tax cuts "will not help his credibility."

“What did the environmentalists see over the last two years?” he asked. “A proposed monumental increase in subsidies for nuclear power industry and offshore drilling."

As for gay voters, he said: “What they got to see was a judge order that 'don't ask, don't tell no longer be enforced and a Democratic president appeal that decision. That is what that constituency saw before Nov. 2.” (The law was repealed in the final hours of the 111th Congress.)

By Election Day, Democratic voters in many districts felt that they had no real choice, Mr. Grayson said.

“If you want people to support you, then you have to support them,” he said. “You have to think long about what you did for people who voted for you, made phone calls for you, who went door to door for you.”

As for waging another campaign in 2012 to reclaim his House seat, Grayson said he will run "if that's what people want."

Some on the left have even thrown his name out as a potential primary challenger to Obama in 2012.

Given Grayson's proven fundraising prowess and ability to pump his own money into a campaign, most observers expect him to make another run at some point. 

Either way, don't expect Grayson to fade from the public eye even if he doesn't run again in 2012. He's already indicated that he'll remain a mainstay on cable news.
