I don't know about the rest of the poll, but the first question quoted is biased by the inclusion of a leading statement about critics' views. This question wouldn't have made it out of the gate in a first-year social science student assignment even. Google "push polling". It violates standards of survey research such as ESOMAR's http://www.esomar.org/uploads/pdf/ESOMAR_Codes&Guidelines_OpinionPolling_v5.pdf.
Judged on this alone, It looks like the "Institute" that did this poll is a sham, and the ScrippsNews papers of suspect objectivity. Kids have a hard enough time in school without being made a political football.
