How successful was Jimmy Carter?

60 Minutes recently had an interview with Jimmy Carter, who is regarded by many, particularly conservatives, as one of the most unsuccessful presidents in history. But did you know that he "normalized relations with China; brokered a peace treaty between Israel and Egypt [I already knew that]; [and] deregulated railroads, trucking, airlines, and telephones"? And his "energy conservation programs resulted in a 50% cut in imported oil, down to just 4.3 million barrels a day." (He actually installed solar panels on the roof of the White House, which Ronald Reagan later removed.) Carter had more of his programs passed than Reagan, Nixon, Ford, Clinton, and both Bushes.

So why, then, do people generally think his presidency was a failure? See what he says in the interview:
