Obama is best of the 3 presidents I've lived through.
Worst: Bush, Reagan, Nixon... Most of the other oldies mentioned, plus I think Grant is generally regarded as a pretty poor president?
Also not a fan of Jackson.
Grant as in Ulysses S. Grant? He was good but severely underrated, he was anti Slavery and worked side by side with Abraham Lincon to end the Civil War he also served two terms as President
Ignoring the Vietnam War, LBJ was an amazing President and his Great Society movement was probably one of the greatest things the United States has experienced within the past sixty years.
