SEDONA, Ariz. – Republican presidential candidate John McCain is spending Saturday at a resort hotel in Sedona, Ariz., preparing for his second debate with Democratic nominee Barack Obama.

The Arizona senator plans to stay for the weekend at his family retreat outside Sedona. He took a motorcade to town and is devoting most of the day to preparing responses to possible questions at the debate and polishing his message.

Obama and McCain are scheduled to meet Tuesday at Belmont University in Nashville, Tenn., for the second of three debates.

The televised debate moderated by NBC's Tom Brokaw will feature issues raised by audience members and submitted by Internet participants in a town-hall format.
