There is only one debate scheduled for the "third-party candidates" and it's tonight at 9pm at the Mayflower Renaissance Hotel in Washington.
I wish I had a handful of worthwhile prizes I could give away. I would walk the street asking people to name four people running for president in 2008, and watch their eyes go blank. I'm guessing a lot of people would misunderstand the question and say "Obama, Biden, McCain and Palin."
There are, in fact, six people running for president, and four of them were invited to tonight's debate. Two of them, Ralph Nader (independent) and Chuck Baldwin (Constitution Party), have agreed to appear. Bob Barr (Libertarian Party) has a scheduling conflict, and Cynthia McKinney (Green Party) hasn't replied.
The debate will be carried on C-SPAN. If they were all there, for sure I'd watch it.
