In Iowa City, John Edwards gives a pretty tough speech on Iran and against Sen. Hillary Clinton.

Senator Clinton is voting like a hawk in Washington, while talking like a dove in Iowa and New Hampshire. One of her advisors told the New York Times that was because she was shifting from primary mode to general election mode. Well, we only need one mode from our president - tell the truth mode all the time.



That's an echo from last weekend's Democratic debate.

The content of this speech differs markedly from a set-the-table address Barack Obama gave in South Carolina on Friday.

I am running because of what Dr. King called "the fierce urgency of now." I am running because I do believe there's such a thing as being too late. And that hour is almost here.



Two different visions of Hillary Clinton, two different candidates, two different ideas about how to beat her.
