Win the nomination, that is. Mark Blumenthal looks at the polls:
Palin has a relatively large base of enthusiastic supporters. Twenty-four percent may not be enough to win a nomination, but a base that size is a strong start towards a potential victory in crucial early states like Iowa or South Carolina, where the winner may receive only 30 to 40 percent of the vote. Second, nearly three out of four Republican survey respondents remain at least open to the possibility of supporting Palin. That means her hardcore opposition is not yet large enough to pose an absolute barrier to winning over a majority of Republican primary voters.
Given her negatives, it's still unlikely. But we should not rule it out, as the Washington Village has. My own scenario for her emergence: an economy losing steam in the next eighteen months, a possibility given new and alarming life by recent economic data. If the number is going in the wrong direction on election day, Obama's in trouble. Notice too the resilience of the "wrong track" numbers. Not good for an incumbent.
