Woodrow Wilson is on track to go down in history as the beginning of the end of the United States. The Federal Reserve act became law on his watch. His incompetence at Versaille set the stage that led to WWII and gave us the worse than useless UN. The XVIth and XVIIth Amendmendments were passed. The combination of these two amendments and the Federal Reserve Act made socialism possible in the United States. A serious case can be made by any competent thinker that Wilson could be held accountable for a claim to being the "worst".
The problem of naming Wilson as the "worst" means there is no place in the ranking low enough to put Franklin D. Roosevelt. Roosevelt is the father of US socialism, and socialism is the cancer that is killing the United States, even as we speak.
And that still leaves the problem of William Jefferson Clinton. If the US manages to survive for more than another decade, China will reach super-power status. A strong case can be made that WJC betrayed his country and made it possible for the Chinese communists to acquire technology to which they otherwise could not have gained access. And it is probably true that the technology they acquired could make them a genuine military threat to the United States when they otherwise might have required additional decades to become a legitimate military threat on their own. A very strong case can be made that WJC traded the technology in exchange for the Chinese making adequate campaign funding available to keep Clinton in office long enough for the complete transfer of all the technology the Chinese needed to close the gap including the acquistion of super computers.
Buchanan the worst? In the Democrats' dreams!
Don't know much about J Buchanan. Why would some consider him the worst?
