Clearly an admission of PDS (Palin Derangement Syndrome), Milbank proposes to heal himself by going cold-turkey. He (rightfully) believes that she has become of outsized importance on the national scene, but he completely misdiagnoses why. It isn't because he and others write about her too much--it is because they write about her with venom and vindictiveness. Rather than covering her in a balanced, non-judgmental way as a major political figure of the right, she is subjected to calumnies and criticisms that flow from a well-spring of elite disdain.
Try simply covering what she says, Mr. Milbank, rather than attempting to mash what she says into a personal narrative of dysfunction.
