Wow, difficult to say. I admire Nixon. I've never understood the hatred of him. He balanced conservative and liberal policies quite well and was quite skilled in foreign policy. There were some ugly things that happened during his administration, such as the overthrow of Allende and the installation of Pinochet as a puppet in Chile. I suppose it was necessary to stop the spread of communism, though. I admire Carter as well, because he told the American people things they didn't want to hear, such as their excessive consumerism was unsustainable. I say it's probably a tie between the two.
