Oprah Winfrey and Barack Obama spent the day campaigning in Iowa today.  I know a lot of people will be excited to witness Oprah's star power, but should it matter?  Who cares in Oprah likes Obama?  The last time I checked, she was one person with one vote.  Any airhead who lets a celebrity endorsement determince their vote needs to have their head examined.  Politics are already corrupted by money, and with the attention given to the Oprah endorsement, I'm afraid that celebrities will continue to poison the political arena.
