Lieberman refused to listen to the wishes of CT voters in 2006 when they voted him out during the primary. Instead, he took a bunch of $$ from special interest groups and the GOP, and somehow won the election - while promising he'd investigate the response to Katrina.
He never did that investigation. He's done diddly as the chair of the Homeland Security Committee.
Lieberman is a blackmailer and a hostage taker. The whiny little viper should have been cast out with his sagging nutsack in his hand, to go join the GOP.
