I am so far to the right of Leibermans politics, but his support of efforts that protect America from terrorists trumps all else IMHO, which is why I plan to (gulp!) vote for him in November.
I'm going to have to gulp before I vote for him as well. I have both philosophical reasons (he's a lib to the core) and personal reasons (he railroaded a friend when he was AG), so it's going to be a bitter vote.
