Naw....that would be Jimmy Carter....Bush Jr is the most hated in the last hundred years...
Carter went into the White House without any working knowledge on how to work with the Congress and the Senate. He was stonewalled every step of the way. I also tend to believe that Presidents get way to much credit for when things go good, and way to much blame for when things go bad.
There are things that Bush Jr. has been a part of that are 100% his responsibility, mainly the Iraq war. He went out every day and sold it to the American people. He was active and vocal in calling the nation to support war on Iraq.
This country was plunged into an unnecessary war. Rather than looking at containment for rouge states, Bush foolishly thought he could bring about regime change which entered into 'nation building', something that has proven track record for not working. Eventually even hard hitting conservatives like Bill Buckley and George Will have seen this as a mark on our country.
