i'll buy that for a dollar...

cenk uygar (yup!), by way of favored link "eat the press," pretty much summarizes it as succinctly as it can be:

"We are not against Joe Lieberman because we are leftists who require ideological purity. We are against him because he aids and abets an out of control Republican Party."

The deal of course is maintaining a consistent mantra when dispensing talking points -- just ask the repos -- and this works for me, and ought to for each and all left-of-center talking heads answering to the more dimly-witted of the political press corps...

UPDATE:

whoa! uygar's summation of all that is wrong with joe lieberman is brilliant... ! and i'll link to it as soon as i figure out how via my mac... in the meantime, do read it!!
