How can Edwards effectively compete with Obama?

[Clarkie1]

I mean, seriously folks. Edwards strengths are youth, charisma, and his "one America" message. Obama has youth, charisma, and an even stronger "One America" message that comes through clearly in his new book in his discussion of the aftermath of Katrina, for example. Obama worked several years in inner-city community development, understands poverty, and is dedicated to fighting racial and economic injustice.

How can Edwards offer his supporters anything that Obama doesn't? It seems to me they both will attract voters who have the same priorities, and are not concerned with their lack of executive leadershp experience and foreign policy credentials. Obama is on the rise, and Edwards and either static or slipping. I think most potential Edwards supporters will be drawn to Obama before they have a chance to cast a vote for Edwards.

Am I way off base here?
