2. Carter - that economy was really awful, we almost hit a Hoover tailspin
5. GWB (Jr.)
SMH.
I took a running jump shot at a full ranking, but I will say that the only intervening presidents I have are LBJ and Ford.
I don't know where Ford ranks, I just slotted him at 4 because he had a short term and he pardoned Nixon. He did hold the country together though. So that leaves LBJ.
People who are ranking GWB Jr. as No. 1 or No. 2 based on what he did with/to/before the Iraq War have got to back up and compare the Iraq War vs the Vietnam War and what was done there.
JFK/LBJ/Nixon & Vietnam War - Gulf of Tonkin Resolution (makes the Iraq runup look like a model of transparency and debate), War Deaths 57,000+, and 150,000+ War casualties
vs.
GWB & Iraq - Full Senate authorization and long debate, with the current Demo VP & 2 SOS's voting for, 4400+ war deaths (3500 under GWB, 900 under BHO)
Rank Carter however you want but Iraq cannot hold a candle to Vietnam in terms of damage done, the lies told (especially by LBJ & Nixon) and the effect on this nation.
If you're looking at the economy also though you have to bring Carter back into the conversation.
