Memory Hole?

Intercollegiate Studies Institute performed an annual “Civics Literacy” survey for six or seven years in a row, tracking trends in the general population with isolation of various demographics. While all demographics showed levels of civics literacy that would not be able to pass the dumbed down quiz prospective naturalized citizens are required to take, two things stood out to me:

1. High School seniors consistently out-performed college seniors, and
2. The lowest scoring demographic was. . . elected officials.
