Oprah again!

After few more months, Obama picked Oprah to be his candidate club.

As the article claims, she can sell books, and now the question is whether Oprah Winfrey can sell a politician.
Barack Obama confirmed today that Winfrey is to join him during his campaigning in three key states next month for the Democratic party's nomination for the US presidential election.

But again??? Were is the originality of politicians? when will they stop repeating themselves?
