Oprah's gaze turns to politics

There is much to admire about Oprah Winfrey. Born in a small, rural Mississippi town, she worked hard to prove herself as an actress and talk show host. To her credit, she succeeded where many others have failed, both in terms of her career and as a successful businesswoman.

But there is also much to criticize about Oprah, especially her recent decision to back Democratic presidential candidate and Illinois Sen. Barack Obama with her money.
