By Associated Press 3:19pm, September 22, 2010Republican Senate nominee Christine O'Donnell is scheduled to debate her Democratic rival Chris Coons at the University of Delaware in mid-October.
University officials say the 90-minute debate on Oct. 13 will be moderated by CNN anchor Wolf Blitzer and Delaware First Media news anchor Nancy Karibjanian.
The race to fill the seat once held by Vice President Joe Biden has garnered national attention since O'Donnell upset nine-term U.S. Congressman Mike Castle in the Sept. 14 primary to snag the Republican nomination.
Sen. Ted Kaufman, a former Biden aide, was appointed to the seat when Biden became vice president but Kaufman declined to run for election.
