Oprah will officially hit the campaign trail for Obama.
(CNN) - Sen. Barack Obama dropped the hint last week, but Monday his presidential campaign made it official: talk show host Oprah Winfrey will join him on the campaign trail next month.
The campaign said Oprah will make four appearances with the Democratic presidential candidate in three key early states: Iowa, New Hampshire and South Carolina.
The stops will be the weekend of December 8th and 9th, in Des Moines, Cedar Rapids, Manchester and Columbia.
Winfrey has made no secret of her support for Obama, who lives in her hometown of Chicago. She officially endorsed the Illinois senator earlier this year and hosted a star-studded fundraiser for him in southern California in September, bringing big bucks and plenty of media exposure.
Her appearance comes as Obama fights with Democratic frontrunner Hillary Clinton for the critical women's vote. A new Washington Post-ABC News poll showed the two separated by just a point among women in Iowa.
