We hear from the Edwards campaign that he's planning to revamp his 2004 "two Americas" theme in a speech tonight that will center on a variety of proposals designed to turn "two Americas" into "one America."

"I have learned something in the last four years," he will say, according to advance excerpts of the speech sent to us by the Edwards camp. "It'?s not enough to talk about the Two Americas. We also need to talk about what we need to do to build One America ?and to do that, I believe we have to build One American Economy."

One key thing -- though not the only thing -- on the agenda tonight: Edwards is planning on proposing a "Family Savings and Credit Commission" which would help those who are the target of abusive lenders and to otherwise help those who are borrowing and investing.

"We should start with the Wild West of the credit industry, where some abusive and predatory lenders are robbing families blind," Edwards, who's made poverty the center of his campaign, will say in tonight's speech at Cooper Union in New York City. "It?s time for a new sheriff in town.?"

More details later as we get them.
