Oprahs Back

ALBUQUERQUE – Oprah is on the way.

On Sunday, Oprah Winfrey is returning to the presidential campaign trail to headline a California event for Senator Barack Obama. The Obama campaign has yet to announce details, but people familiar with the event say the television talk show magnate will join Michelle Obama at a campaign rally in the Los Angeles area.

The goal? Closing the gap with Senator Hillary Rodham Clinton in California before Tuesday’s primary. The target? Women voters.

It has been nearly two months since Ms. Winfrey made her debut on the trail, drawing tens of thousands of people to arenas in Iowa, New Hampshire and South Carolina. Mr. Obama won Iowa and South Carolina, which aides attribute to the attention stirred by Ms. Winfrey. (Particularly the landslide South Carolina victory.)
