Yesterday, but I'm behind...but yeah, Steve Benen is right that it really is astonishingly silly to poll on how long Barack Obama's rally-round-the-flag poll bounce will last. He went with "deeply silly," but I guess there really are a lot of appropriate adverbs for it.
Very small value added for this post: I'll make the fairly obvious point that there's some opportunity cost in polling on one thing and not the other. In fact, there are plenty of things about which I'd be curious to find out what the American people think, but we have no polling. This one? Not so much.
Anyway, good catch.
