Herr Liebermannikin must be forced to leave the race for his seat to the party's choice -- and ambitious Senate folks like St Hill, Biden, Kerry, Feingold, Obama better damn well demand it of him. And if he fails to act quickly they better damn well renounce the Lieb publically, right away, and throw him out of the Senate party caucus.
For each one that doesn't toe this line, let there be a symbolic branding -- "here slides a Joe-mentum sidewinder."
