Don't get me wrong. Bush isn't doing a good job. But, aside from the war (which some would say is going much better now), every screw-up he's had pales next to the failures of Carter.

Furthermore, Carter may not have started a shooting war, but his bungled handling of foreign policy, from the Soviet Union to the Middle East (most notably the Iranian situation), planted the seeds for nearly ever problem that subsequent Presidents, including Bush, have faced ever since.

Add in a shitty economy, scandals in his administration and his whining about malaise (effectively blaming the American people for his own failures) and there's little doubt that Carter is the worst.
