Five worst US Presidents, IMO
Barack Hussein Soetoro Odinga Whatever 0bama.
James Earl “Jimmah” Carter
Franklin Delano Roosevelt
Woodrow Wilson
(Tie) Theodore Roosevelt and US Grant
Dishonorable Mention: Abraham Lincoln
Your list and mine have two bad presidents in common: Wilson and Obama. My list also has LBJ and George W. Bush.
LBJ for his mishandling of Vietnam, and George W. Bush for his failure to stamp out radical Islam. While Vietnam was certainly a tragedy, W’s failure in regards to Islam will haunt the West for decades - and maybe centuries - to come.
As to number 5 on my list, I’m still trying to decide between Buchanan and FDR. Buchanan’s bumbling helped bring on the Civil War, but perhaps that was inevitable.
FDR expanded the socialist welfare state, but IMHO he was the right man at the right place during the early days of WW II.
Mandatory disclaimer: Your mileage may vary.
You forgot Billy Jeff! I would definitely put him before Teddy and Grant.
