Senator Dodd is a class act.  He withdrew from the race and the following is part of his statement via Daily Kos:

"But there is no reason to hang our heads this evening -- only the opportunity to look towards a continuation of the work we started last January: ending the Iraq War, restoring the Constitution, and putting a Democrat in the White House.

"I know a lot of you came to this email list through a shared desire to return our nation to one that respects the rule of law, and I want to make one thing clear to all of you:

"The fight to restore the Constitution and stop retroactive immunity does not end with my Presidential campaign. FISA will come back in a few weeks and my pledge to filibuster ANY bill that includes retroactive immunity remains operative."

Thank you, Senator Dodd. 

Senator Chris Dodd continues to fight this important battle.  He should be the Senate Majority Leader.
