Bush not the worst president ever; Franklin Pierce was...followed in order closely by James Buchanan, Millard Filmore, Warren G. Harding, Jimmy Carter, Herbert Hoover, Richard Nixon, U.S. Grant, Andrew Johnson, Bill Clinton, LBJ AND THEN George W. Bush. But, then again, Byrd would have probably have put Jefferson Davis somewhere in the top for best honors and certainly backed David Duke if he ever wanted to run for the office.
You really need to move LBJ up that list several notches.
