Via The Fix…

Not only has Lieberman endorsed Sen. Susan Collins (R-Maine.) -- one of Democrats' biggest targets in the 2008 cycle -- but he's planning to co-host a fundraiser for her on June 21 in Washington, D.C.

Collins did, after all, smudge, if not actually cross, party lines to support Joe against Ned Lamont.

And there's the self-preservation instinct. Turn one more seat and Joe Lieberman becomes the least relevant human being in Washington, D.C.

Without a US Senate race here in the upper left in '08, I've been casting around a bit for one to adopt. Right now it looks like this one.
