With her defiant video, Palin continued—no, escalated—her war with the press, which plays so well with her strongest supporters (despite a recent thaw in which she actually granted a few interviews to the lamestream media). She continued her us-versus-them approach to political discourse. She punched back at critics rather than trying to fashion a unifying message.

I would say that sounds like the response of someone who wants to stoke her base and further her lucrative career as a culture warrior—not someone who is plotting to run for president.
