2012 White House race 'nastiest' ever- McCain

US: The Republican campaign to choose a candidate to take on President Barack Obama in November is "the nastiest" ever, presidential campaign veteran John McCain said Sunday.McCain should know -- he was the target of a barrage of destructive rumors himself in his losing 2000 campaign against George Bush to become the Republican presidential candidate.

In an interview with NBC's "Meet the Press," he blamed the mudslinging on the so-called "super PACs," which can raise and spend unlimited sums in support of a candidate so long as their campaign activities are not directly coordinated."The super PACs have played a key role, unfortunately in my view, because most are negative ads, (have) driven up unfavorables of all the candidates and made it much more difficult to win the election," McCain told NBC television's "Meet the Press."
