Sen. John McCain, who ran for president in 2000 and 2008, said today that the race to determine the 2012 GOP presidential candidate is “the nastiest I have ever seen,” CNN reported.

“It’s gone way too long and gotten way, way too personal,” he said on NBC’s “Meet the Press,” National Journal reported. “Attacks on character and all of that have been very unfortunate. And, again, who has benefited from it? President Obama.”
