Who IS or WAS The Best President of The USA ?

Franklin Delano Roosevelt
comment: some of the programs he started are still in use today.

Donald Trump is best of all !

Most historians say Abraham Lincoln, Franklin D. Roosevelt, and George Washington are some of the best, but what's best is up to you. I say if you really wanna know you gotta research presidents. All 3 of those presidents have flaws, and it's personal opinion whether you can look past their flaws or if the flaws bring them down. I, for one, dislike FDR because of Japanese Internment and other stuff in WW2 because of my own values, but the beauty of it is that is just one person's opinion, and other people who've done research can say the exact opposite and have it still be true. 

If you for for the one in office he is the best ever. If you didn't he's the worst ever. It's called hyperbole.

There is not one, a right answer, timing plays a role, economic, social measurements are different, times are different. Americas tech age under Clinton was awesome economically. But was that due to the tech or to Bill. His tax policies at the time made it a hell of struggle to break out above 100 thou for those regular joes trying to climb.  People also tend to forget that at the end, there was a down turn in the economy. That Turned into the Bush giving back the people their money. Then finding out the surplus wasn't real, just fuzzy math. Big oops.
