No, seriously: Time to kick Joe Lieberman out of the Democratic caucus

Exactly what do Democrats gain by keeping him in?

Sounding more like an independent than a Democrat, Sen. Joe Lieberman, I-Conn., tells ABC News he will campaign for some Republican candidates during the 2010 midterm elections and may not seek the Democratic Senate nomination when he runs for re-election in 2012.

“I probably will support some Republican candidates for Congress or Senate in the election in 2010. I’m going to call them as I see them,” Lieberman said in an ABC News “Subway Series” interview aboard the U.S. Capitol Subway System.

So, Harry Reid: Joe Lieberman is working against you on domestic priorities. He’s against you on foreign policy priorities. And he’s stumping against your candidates. What’s the upside?
