Oprah won't support Obama in 2012?

Oprah Winfrey reportedly does not plan to publicly support Barack Obama in the 2012 US presidential election.
Winfrey supported Obama's campaign in 2008, holding a highly publicised political rally for him during his presidential challenge.
According to a Gallup poll conducted before the rally, Winfrey's favourable ratings fell from 74 to 66% while her unfavourable ratings jumped from 17 to 26%.
Her TV show ratings also fell following the event.
A source has told PopEater that Winfrey doesn't want to do anything to alienate viewers now that she has launched her OWN network.
"For 2012, much has changed for Oprah. She now has her own cable channel called OWN that has been struggling to find an audience - she isn't going to do anything to alienate them," the insider said.
The source added: "Unlike in 2008, when a drop in ratings didn't matter as much for the queen of TV, Oprah is now fighting every day to get people to tune into OWN."
The source continued: "Helping a friend keep the most important job in the world is great, but making sure her OWN network thrives is now her priority."
Judge Judy defeated Oprah in the ratings last season to become the number one daytime TV series.
Earlier this month, Chicago-based Harpo Productions revealed that the final episode of The Oprah Winfrey Show will air on May 25.
