Today's polls confirm that poll findings during the past ten days have reflected a post-convention, post-Palin bounce. And now it's over.
In case the image isn't clear, Obama is now back up by two according to the Gallup daily tracker. I have no idea what will happen henceforth, but to take my victory lap, this is pretty much what I expected.
Update, 9/18: It's now at four, 48-44. Bonus findings: Palin's favorability is tanking.
