Battleground state faces a busy week

Democrat Barack Obama's campaign announced Saturday night that he'll return to the Tar Heel State Wednesday, one day after a visit by Republican John McCain.

Need more proof that North Carolina, entering the campaign's final days, is a battleground state?

Their respective running mates, Sarah Palin and Joe Biden, also are here this week.

Today, Palin appears at an evening rally at the Asheville Civic Center.

On Monday, Biden stumps in Greenville and Greensboro.

Tuesday, McCain will speak at an afternoon rally in Fayetteville.

And on Wednesday, Obama and his wife, Michelle, attend separate events in the state.

Michelle Obama speaks in Fayetteville and Rocky Mount. The location and other details of her husband's appearance have not been announced.
