That's what my parents have always said, but I haven't really delved into what the reasons are. Jimmah Carter has always gotten my vote as the worst President, even x42 was too paralyzed by his inadequacy/intern scandals to effectively promulgate much of lasting harm (apart from selling our nuclear secrets to the Chinese, I mean).
Wilson gave us the Federal Reserve, Federal Trade Communion, Federal Farm act and was in the KKK set up laws that created the racists hate we have today (race relations where getting good before he got into office.)
Wilson got us into WWI then created the treaty of Versailles which he got the noble peace prize yet because of that treaty we entered WWII. He created the Bryan-Chamorro Treaty which destabilized central America. The list just goes on.
