James Fallows on the birth certificate idiocracy:

Yesterday, about half of all Republicans thought Obama was foreign born, and therefore an illegal occupant of the White House. How many Republicans will think the same thing one week from now? My guess is: about half. […] Here we have a wonderful real-world test: if “actual knowledge” mattered, the number of people who thought Obama was foreign-born would approach zero by next week — with exceptions for illiterates, the mentally disabled, paranoid schizophrenics, etc. My guess is that the figures will barely change.
