Top notch investigative work by a group of bloggers has discovered that the Palin smear campaign traces back to close associates of Barry Obama. Michelle Malkin summarizes it better than I could.

First, read this. Read the whole thing. Rusty Shackleford — with help from Jane of Armies of Liberation, Stable Hand, the Jawa team, Dan Riehl, Ace of Spades, and Patterico – traced a Palin-bashing YouTube video to a Democrat public relations firm, Winner and Associates, and one of its employees, Ethan S. Winner. They believe the voiceover for the ad — which spreads the lie that Sarah Palin belonged to a fringe third party, the Alaska Independence Party — was done by a professional whose voice they believe was also featured in several Obama ads and other spots produced by Obama top strategist and astroturfer extraordinaire David Axelrod’s firm.
