After reading Sarah Palin's memoir, John McCain likened the strain of a campaign to war.
"In campaigns there's always tension. Outside of combat, it's the most tense situation. There's always differences that arise, but it's no big deal."
And he still like his former running mate.
"I enjoyed the book and she and I are dear friends. I talked to her on the phone yesterday. We got along fine."
