WASHINGTON (September 30, 2012)—U.S. Sen. John McCain, R-Ariz. says viewers should not expect any surprises in this week's first presidential debate because the televised confrontations nowadays are so heavily scripted.

McCain, who ran against Mr. Obama's in 2008, said says if he were running against Mr. Obama again, he could easily guess and prepare for the first half-dozen questions because they are usually so obvious.

McCain said he still thinks debates are good for the country and the elections, and he predicted that Wednesday's debate between Mr. Obama and Romney will attract the largest number of viewers in history.

But, he said, if Americans are expecting to catch any revealing moments, they might be disappointed because "frankly the candidates are too well prepared."

McCain spoke Sunday on CNN's "State of the Union."
