Edwards will run a 60-second closing ad tomorrow and Thursday during the network evening news programs on local affiliates in Iowa. It features a laid-off Iowa Maytag employee -- Doug Bishop, who at points chokes up during an introductory speech -- laying out the case for Edwards, that the candidate looked his 7-year-old son in the eye and said, "I'm gonna keep fighin for your daddy's job. I promise you that.'

"You know that stuff sticks with you," Bishop says, "That's the kind of things we need in a leader in this country. Not somebody that's going to go to a big fundraiser and says write me a check for $2,300, and I'll let you know you have my support." Bishop later says, "I'm gonna do my best to make sure that my children aren't the first generation of Americans that I can't look them in the eye and say you're gonna have a better life than I had."

The ad effectively summizes Edwards' strategy and message, as he has courted and shown support among stalwart, blue-collar Democrats.

Edwards is also running a full page ad in today's Des Moines Register featuring Bishop.
