Writes Arianna her ownself: "We have learned the video was the work of Philip de Vellis, who was the Internet communications director for Sherrod Brown's 2006 Senate campaign, and who now works at Blue State Digital, a company created by members of Howard Dean's Internet Team."
And Arianna was kind enough to let de Vellis blog about it: "Hi. I'm Phil. I did it. And I'm proud of it."
Considering that someone calling himself ParkRidge47 was the first person at Huffington Post to notice the video... way back on March 5 ... why should anyone be surprised HuffPo got this scoop? I'm with this guy and his conspiracy theory. Oh, but wait, there's more!
