The Rasmussen Reports recently asked Americans whether they have favorable or unfavorable views of every president from George Washington to The Decider. Naturally, Washington and Lincoln are the tops. Nixon and Bush are, well, not. The winner of the "not sure" category, with 74% not sure, is the guy in the picture. (Rhymes with Tohn Jyler.)
UPDATE: The McKinley error has been corrected. He received a response of "very unfavorable" from 4% of respondents, not 40%.
