Actually, not really. Just a question on how to make them go away.
I have two predictions:
1) Someone like Ross Douthat will say that birferism is somehow liberals’ fault, the same way it was liberals’ fault for killing the George Tiller by supporting reproductive rights.
2) Birther opposition will be used as a sign of credibility by wingnuts when the next whacky rumor crops up, e.g. “I’m not a conspiracy theorist, I speak as someone who strongly opposed the birthers when I say that the footage of Obama fathering an alien baby looks very real to me.”
