That’s not much of a surprise if you’ve observed conspiracy theorists for a while. People still think the moon landing was a hoax, and don’t even mention the Kennedy assassination unless you’re prepared for ever-more preposterous “explanations” that Lee Harvey Oswald couldn’t possibly have acted alone.
But it’s annoying that a large number of Republican officeholders still can’t bring themselves to admit that birtherism is, was and will be nonsense.
