I've already gone on and on about Joe Lieberman and what a Judas he is to the Democratic Party, so I won't go on at length about that again, but rather, I'll say that this is now the second time since commanding a significant majority of the vote and obtaining quite the political mandate that the Democrats have pussy-footed around the right solution just because they don't want to be thought of as rash. Don't be so silly! People elected you because they wanted you to clean up some of the old messes! If you don't do so, you won't be in power for very long. Keep that in mind.
When someone stabs you (whether it's in the back or in the front) it's not your job to still be their friend. I thought most of us learned that in middle school.
