Michael Dannenberg, senior fellow with the New America Foundation and a former adviser to Sen. Edward Kennedy, D-Mass., says Obama's proposals take the problem of college affordability more seriously than McCain's. And he calls the tax credit a significant innovation. 

"McCain's message when it comes to increased tuition is, 'You're on your own,'" said Dannenberg, who has not worked for Obama's campaign. "Obama's message to families is, 'We'll give you more financial aid to help you with college costs, but your kids are going to have to help others.'" LINK
