The USA is better off because Joe Lieberman is in the US Senate.
Although he is a liberal on nearly all social issues, he can be counted on as far as national security policy and many fiscal issues.
Lieberman is infinitely better than Ned Lamont would've been - and Lamont would've been elected had not Joe sought and won election as an independent.
It is better to have a liberal you can count on on the most important issues, than a liberal you cannot count on at all.
The same is true of Castle: he is better than the Democrat alternative.
And only he can win the general - and beat Delanware's Democrat nominee.
That's why - in a way - a vote for Christine O'Donnell is a vote for Ned Lamont.
