"The old politics of partisan polarization won today," said Lieberman.

Joe's right: A Republican got beat by a Democrat. Doesn't get much more partisan than that.

Update 1:10 AM ET: From the Hotline blog:

A senior Republican official in Washington confirms that the party might encourage Republicans and others to support Sen. Lieberman if he runs as an Independent . . . And Kevin F. Rennie reports that some GOPers in CT are thinking about ways to financially support Lieberman's independent bid.

See what I mean?
