Wha'? We've been to the moon?

On the unreliability of polls: "Don’t forget there are measurable minorities of Americans who will tell you not only that Obama is a Muslim but that the Holocaust never happened and nobody ever landed on the moon. Don’t forget, highly reputable surveys have found Republican voters making Donald Trump their frontrunner for the party’s presidential nomination. Ye Gods! At the moment, a poll shows 62 percent of Americans are opposed to raising the debt ceiling. Does anyone imagine that many citizens know how the debt ceiling works?" (Jack W. Germond, The Daily Beast)
