"What’s the f------ point? Keep the fight up?" asked McCain about Clinton's retrospective, entitled "What Happened."
McCain, who knows firsthand what it's like to lose a presidential election, told Esquire that "one of the almost irresistible impulses you have when you lose is to somehow justify why you lost and how you were mistreated."

Unlike Clinton, McCain did not follow up his election loss with a book chronicling his campaign, though his former staffers did.
"The hardest thing to do is to just shut up," McCain said about losing the election.
But McCain also seemed to place some of the blame for Clinton's media blitz on her relatively empty schedule. When McCain lost the election to Barack Obama in 2008, he returned to work in the Senate.

While Clinton is involved with her family's charity and countless other initiatives, she does not have any official job in the government following her loss.
"History will judge that campaign," McCain said of Clinton's 2016 run. "It’s always a period of time before they do. You’ve got to move on. This is Hillary’s problem right now: She doesn’t have anything to do.”
