More on the Clinton-Obama Debate Over Rhetoric

In hard-hitting media conference call, Clinton-backing Rep. McGovern implicitly compares Obama to an "American Idol" contestant.

At issue: Obama flip-flop on general election public financing and now-famous YouTube clip (above) in which Obama echoes words of Massachusetts Governor Patrick.

Clinton's Wolfson: "If you're asking the public to judge you on your rhetoric and your promises and you are breaking your promises and lifting your rhetoric, there's not much else there." More Wolfson quotes and audio here.

Firing back, Obama campaign releases list of Clinton borrowing Obama's language, including this video.

Obama in radio interview with Ed Schultz: "My friend Governor Deval Patrick -- he and I, we exchange ideas and words all the time. I used a riff he has used before. That's the extent of it."

Obama campaign manager Plouffe: "This is an effort to create distractions. They're grasping at straws."
