Women should not feel guilty if they prefer Barack Obama over Hillary Clinton… so says Oprah Winfrey.

During a rally in Los Angeles, Winfrey said, "Every part of me believes in the empowerment of women. But the truth is I'm a free woman. Being free means you get to think for yourself and you get to decide for yourself what to do." She said women who had already planned to vote for someone else – that would mean Hillary – had "the right to change their mind."

Winfrey described how she was criticized by some women after she campaigned for Obama in Iowa. She says they called her a traitor to her gender.

Oprah participated in a huge rally for Barack Obama yesterday along with Michelle Obama, Caroline Kennedy and Maria Shriver – wife of California Governor Arnold Schwarzenegger.

This is all part of a push by the Obama campaign to reach out to women voters. That's because women are expected to make up about 55% of Democratic primary voters. And in a state like California, where Obama has now come within striking distance of Clinton, more support from women could make the difference.
