Joe Lieberman, the chameleon from Connecticut

After bashing Obama at the Republican National Convention and by John McCain's side on the campaign trail, Joe Lieberman has changed his tune:

Sen. Joe Lieberman has changed his tune on Barack Obama. After campaigning across the country for Republican John McCain in 2008 and attacking Obama as naive, untested and unwilling to take on powerful special interests, Lieberman now showers praise on the popular new Democratic president.

"He's shown real leadership," Lieberman told The Associated Press in an interview. "Bottom line: I think Barack Obama, president of the United States, is off to a very good start."

The Connecticut independent, who faces re-election in 2012 in a state where Obama is popular, is eager to mend fences with Democrats still fuming over his criticism of Obama during the general election campaign.

Lieberman has applauded Obama's national security team. He gushed over Obama's "inspirational and unifying" inaugural. Lieberman even played a key role helping Obama win Senate passage of the economic stimulus plan.

As if to underscore the point, Lieberman has even clashed on the Senate floor with his pal McCain over the stimulus plan and a District of Columbia voting rights bill.
