Barack and Dave Talk Politics and Other Stuff (videos)
I posted the opening segment earlier here, but here are the other two segments of his appearance on 9/10/08. It's interesting that we are turning to progressive radio and the entertainment side of television now (The View and Letterman) for some honest political discussion.
H/t to Darryl.
Howie P.S.: For a much grittier look at today's political scene in the USA, check out Brendan Kiley's report from the streets of St. Paul, "A Funny Thing Happened on the Way to McCain's Speech--Our Skin-Burning, Cigar-Chomping, Douchebag-Studded, Palin-Aghast Report from the RNC."
