Washington (CNN) - Sen. John McCain said Monday he is looking forward to a "very nice reunion" with his former presidential running mate, Sarah Palin, when she campaigns alongside him later this week in Arizona.
Palin will join McCain at two rallies at the end of the week in Tucson and Phoenix, their first appearance together in public since the 2008 presidential race. Former Rep. J.D. Hayworth is challenging McCain in the Republican primary, a race McCain said he is not taking for granted.
McCain told C-SPAN his campaign has received an "overwhelming response of people that want to come to the rallies."
"Sarah did galvanize our party after she agreed to be my running mate, and the speech she gave at the convention," McCain said. "I am sure she will do the same thing when she comes to Arizona."
He added: "It will be a very nice reunion, to have the chance to spend some time with her, and I am very grateful that she would come to Arizona."
