Douthat examines the "limits of Palinism":
[G]iven the choice between saying the thing that broadens her appeal and the thing that plays best with the narrower group that already loves her, Palin always, always seems choose the latter. Conservative writers have been giving her advice on how to break out of this box for more than two years now (this week it was Kevin Williamson, imagining how she might boost her credibility as a presidential candidate), and I think at a certain point we all just need to stop playing make-believe and acknowledge that she isn’t interested. The politician ... on Fox News on Tuesday, never giving an inch and blaming everything on the media, is the politician Sarah Palin has become, and wants to be, and seems likely to remain.
