The Associated Press tells us:
PHOENIX — John McCain and Sarah Palin are scheduled to campaign together in Arizona next week for the first time since they conceded the presidential election in Phoenix in 2008.
Palin and McCain will be at a rally and picnic in Tucson on March 26, followed the next day by a rally in the Phoenix suburb of Mesa.
McCain and Palin have had a couple of public appearances together, including a dinner in Washington, but the Tucson and Phoenix events are their first return to the stump.
The former Republican presidential candidate is facing the toughest re-election battle of his Senate career. Former Arizona Congressman and talk-radio host JD Hayworth is challenging McCain in the Republican primary.
