I'd still put FDR first all things considered. Clinton would be second. Carter gets my nod for worst ex-president. That's certainly an honor the FDR couldn't even compete for. I think we still don't fully understand all the damage that clinton has done so he could conceivably move up but right now I still put FDR first.
And yes LBJ has to be in there somewhere's as well. But I'm sticking with FDR as a lock for the number one position.
I would have to agree on FDR, he started this country on the gimme road. I'd rank Carter ahead of Clinton. Clinton was there for what he could get out of it easily. Carter thought he was so in touch with everything and still does. He undermines our very security, and gave the terrorists courage to start down this road that Bush Jr. is trying to fix.
