Who Was The Most Immoral President In US History ?

There are so many to chose from, so it depends on what angle you're going from, and I'm not even listing anywhere close to everything from all the Presidents.  None who is elected President can let morals keep them up at night.  They all lie and cheat to do what they think most be done.
 
G.W. Bush--tramping on the Constitution and eliminating so many rights and freedoms that brave men and women died to defend
W.J. Clinton--Well, we all know what he did...but not uncommon of Presidents throughout history.
R.W. Reagan--Arms for hostages...well, we did get our people back, but at what cost?  Are our people more valuable than those who died because we traded the arms?
R. Nixon--Breaking laws to ensure that he was reelected President.
J.F. Kennedy--Essentially the same types of things Clinton did.
H.S. Truman--Dropped nuclear weapons on two Japanese cities.
T. Jefferson--Owned slaves, and supposedly had children with some of his slaves.  I don't know how many Presidents owned slaves, or how common it was in that time to have children with your slaves.  Perhaps it was just part of the social norm then.
 

I'm going with Clinton on this one, and not getting into the political side of it.  He did more to wreck what little respect and pride people used to have for the President of the United States, than any other President ever did with their political scams and dealings.  Bill Clinton held the highest position in the United States, a position that is supposed to be executed by acting respectably and morally decent for all the country to look up to, not withstanding the way other countries look upon our leader in the U.S.  He acted like an immoral man who used his position to get his own personal thrills, an adulterous husband, and a pathological liar when he was caught.  He made this country look like it's leader was a total clown and x-rated porn star wannabe.

Jefferson for raping slaves.
