Yeah ..ya got me....
Just because I read "A CNN Poll" and then clicked on your link.... I should know better and read ALL the fineprint when dealing with a true believer
What the Poll did seem to show is that whoever was the current US President would automatically win out, and I suggest that shows a lack of ability to distinguish achievement from popularity by many polled regardless of political affiliation.
Of course, this was only for "living" people, or there would be some other great names to consider.... Gandhi, Mother Teressa, Churchill...all of whom would probably have finished behind the great Jimmy Carter if the poll had been taken in 1978!
