There's a pretty good John Edwards speech broadcast on C-SPAN as part of Road to the White House. I saw it earlier this evening, and it's going to be rebroadcast at 12:30 AM EDT.
He talks about poverty and community in the wake of Katrina. And it's a good illustration of a strong Democratic message that can reach beyond Karl Rove's politics of polarization.
It's also a pretty good illustration of how it's nice to have a great communicator delivering your message.
