Bernstein notes the latest example:
I've talked several times about "playing by the rules." I've said that the main reason Sarah Palin was unlikely to win the Republican presidential nomination was that she refuses to do the sorts of things that candidates for president have to do. Wonderful, wonderful example of this in a post yesterday from David Frum. Frum describes in some detail one group of GOP elites (the Republican Jewish Coalition) and what Palin did to annoy them. The gist of it is that the RJC has sponsored Israel trips for numerous GOP presidential candidates, and that Palin chose to use another group to arrange her trip without even bothering to RSVP to the RJC's invitation.
