Demagogue

Some 30 percent of Americans cannot say in what year the September 11, 2001 terrorist attacks against New York's World Trade Center and the Pentagon in Washington took place, according to a poll published in the Washington Post newspaper.
...
Of that group, six percent gave an earlier year, eight percent gave a later year, and 16 percent admitted they had no idea whatsoever.

The year before or later I can sorta understand, but 16% had no clue? Maybe 16% of the people who responded to this poll were stinking drunk & stoned? Maybe they were Alzheimer's patients? Or maybe they were stinking drunk & stoned Alzheimer's patients?

Otherwise I got nothing.
