Who has been the worst President overall?

[SATW]

For me, it has to be Bush 43, he got us into a war there was no point in fighting, the economy almost completely collapsed during his presidency thanks in part mostly to his policies which ultimately were disasters (Medicare Part D, No Child Left Behind, etc.

My second would have to be Hoover.

This seems to fit you better. I understand why GWB won't be many people's favorite President, but he's not even close to, objectively, being the worst President.

James Buchanan was a disgrace.
John Tyler was a disgrace.
Millard Fillmore was an inept disgrace.
Ulysses Grant was a failure and was corrupt.
Richard Nixon is self-explanatory.
Woodrow Wilson is also self-explanatory.

All better candidates for worst President then GWB.

Was there really anything Buchanan could have done to save the Union though?

SO I should be a Democrat because I can't stand Bush? Lol, ok, I hate Obama as equally as I do Bush for the same mistakes that Bush made, if Bush never wrongly attacked Iraq we wouldn't be having an ISIS problem now would we?

No, you can hate Bush or whatever, but to say he is worse then people like Buchanan or Nixon is ridiculous.
