Which U.S. President do you hate the most?

Well...

Buchanan allowed the civil war to happen. So there's that.

Rutherford B. Hayes allowed basically for the reinstitution of slavery through his removal of reconstruction efforts.

Grover Cleveland was a rapist who publicly slandered his victim.

Andrew Johnson is colloquially known as the most racist president in U.S. history. He was also a disgusting narcissicist.

And Andrew Jackson actually violated the constitution while in office and in doing so committed one of the more egregious crimes against humanity any president has ever overseen (certainly over his own citizenry). He also facilitated one of the longest recessions in U.S. history.

And that's not even getting into the 20th or 21st century...

Bush II.

None.

I have a life.

Going by the definition of hate as extreme dislike or disgust, in my 60 years I never hated a President until Trump.

Hate is too strong of a word. I dislike Ronald Reagan for ruining the economy and selling arms to known terrorists. I also dislike Donald Trump for many reasons; and he is currently tied for first place with Reagan.

Hate is far too corrosive an emotion to be directed towards anybody whose existence has not directly affected yours.

The current version.

Bill Clinton

Toss up between Shrub and Bubba. Donnie is gonna win though if he keeps his "tweet fest to stupid people" going for another year.

Kennedy
