The polls suggest Lieberman losing the General is a real possibility. The poll I saw had Joe and Lamont each at 40% in the General (if Lamont wins the primary, I suspect the next poll will show Joe losing in the General to Lamont). The problem is, yes you guessed it, let's spell it out together - I-R-A-Q. Shays is going down too, I suspect, for the same reason.
Then its going to be a massacre across the board. A Democrat Congress...yuck!
