Watching the Democrat primary in SC, I'll still disappointed that Fred dropped out. While he staked too much on SC, and I'm sure the campaign war chest was empty, so is Huckabee's, and likely McCain's as well. So, he might have made a dent in FL, where I sense Giuliani's campaign is sinking.
My guess: two man race between McCain and Romney after FL.
If Fred is interested (after all, Law and Order probably pays much better than government service) he could be Secretary of State, or head of Homeland Security. Of course Giuliani would be a strong Homeland Security head as well.
