Who shall it be?

Who is the greatest United States president to date?

List all successful administrative policies.

Who were the worst listing the vice versa?

Sure, here is the list:

(List is empty)

Number one is FDR.  Historians laud Franklin D. Roosevelt for his extraordinary popularity and his devotion to economic justice.
FDR assumed the presidency during the worst of the Great Depression, but assured the American people: "The only thing we have to fear is fear itself." He also led the U.S. through the perilous years of World War II. 
He is the only American president ever elected to four terms, though he died before completing the last one.

Trump is third from last.

Andrew Jackson 

Andrew Jackson (1829-1837) was a risk-taker president who was very good at drawing crowds and well liked by much of the public.
A polarizing figure, Jackson waged a political battle against the Second Bank of the United States, a private company which operated as virtually a government-sponsored monopoly. He also pushed for the forcible removal of Native Americans, resulting in thousands of deaths. The American electorate handed him a huge victory for his second term.

False Dick-lobotomy's lead us into the tempation to make choice betwen which president was the worst troll, or the best troll.

Was Roosevelt greater than Trump?

Yes, Roosevelt ranked No. 1 and Trump ranked 43.

Yet Trump is the matter of discussion than him. But he is supposedly the greatest .
