Oprah and Politics

I wonder if Oprah has thought through what she will do if/when Obama withdraws from the Democratic race. Will she forgo commenting on the rest of the race or will she endorse the Democratic nominee. Given the high profile nature of her endorsement, if she refuses to support the ultimate winner, it could be treated as repudiation of that candidate. It is possible that an Oprah endorsement will be used by Obama to secure a place on the ticket? How could she refuses the endorse a Democratic ticket which includes Obama?
