Does Matt Taibbi's Rolling Stone Piece on Michele Bachmann Qualify as Plagiarism?

According to Poynter, Matt Taibbi’s  just-posted Rolling Stone piece on Michele Bachmann “borrowed liberally” from a 2006 City Pages cover story written by G.R. Anderson. City Pages writes that Abe Sauer at the Awl called Rolling Stone out in a “point-by-point comparison and got Rolling Stone executive editor Eric Bates to admit he had deleted several ‘according to City Pages’ references. Bates promised to add link backs into the electronic version of the story, which he did.”
