Quote from Index piker:
Perhaps it would be best to read the methodology of the survey.
http://www.siena.edu/uploadedfiles/...nt_research/Presidents Release_2010_final.pdf
"The Siena College Research Institute (SRI) Survey of U.S. Presidents is based on responses from 238 presidential scholars, historians
and political scientists that responded via mail or web to an invitation to participate."
Its 2010,people communicate by the Internet
The fact that the poll was made from the opinions of Presidential scholars, historians and political scientists and was first started in 1982 is more relevant imo
