Over the last few weeks, Washington conventional wisdom has begun to coalesce around the idea that Sarah Palin won't run for president. A number of news outlets and commentators have pointed out that she isn't doing the sorts of things that serious candidates usually do at this point in the calendar, hiring veteran staffers in the key early primary states, visiting those states regularly, and delivering speeches that begin to lay one's "vision" for the country. Roger Ailes of Fox News pointedly did not suspend her contract, as he did those of two other candidates, because, he said, she has given no sign that she is planning a campaign.
