Barney Frank/Chris Dodd - for their combined work in trashing the US economy
Supreme Court Justices: Warren, Black and Burger for their elevating the supreme court above the constitution
Huey P. Long
Nathan Bedford Forrest & William J. Simmons - KKK
I do agree with Wilson and FDR on this list...the damage they've done to this nation is immeasurable.
Wheres Malcolm X on your list? Wouldn't you say the Black Panthers were and are just as racist as the KKK?
Black and Burger? How about Felix "Positivism" Frankfurter, William O. "Penumbra" Douglas, and Billy "Awww, Come On, You Know You Like Me" Brennan? The worst log-rolling, Constitution-subverting justices in recent history?
And John Marshall started the whole thing rolling. From arguing reserved powers at the Virginia ratification convention, he went to absolutist judicial review and other implied powers on the Court, and doing things like arguing that the "general welfare" clause lets Congress claim any power it likes. He wound up being as bad as Hamilton, and even worse, because Hamilton didn't have an entire branch of the Government behind him.
