anyone who says obama is the worst president of all time is totally biased towards modern times, he's not even close...there are presidents that agreed that black people are 3/5ths of a person, a president who dropped two atomic bombs, a president who contributed to sending the country into the great depression, a president that got into a war in vietnam and lied to the country about why, and more...i don't even hate all of the people i mentioned but obama has never done anything even close to that controversial, what is wrong with you people
and on topic, my favorite is FDR and my least favorite is probably nixon or lyndon johnson
