Sen. John McCain (R-AZ) debated both 2012 presidential candidates in 2008 and gives us a unique perspective as the campaigns try to manage expectations.
"I think it's going to be excellent. I think both candidates are well-prepared, and understandably, you'll see their surrogates lowering expectations, oh, I don't know how our guy will compete, and that's part of the whole routine."
"I think sometimes we expect a major breakthrough, you know, the comment that - that doesn't happen very often. It happened with Reagan and Mondale. It happened with Reagan and Carter."
"Frankly, I can't remember the last time there was one of these comments that grabbed everybody's attention because, frankly, the candidates are too well-prepared. They're well-scripted."
