Tonight, most of the country will be hanging on John McCain's every word. However, some excess of 2,000 people will take their seats in Minneapolis's Orchestra Hall where Cindy Sheehan, Nellie McKay, Jesse Ventura, David Rovics, Ike Reilly, and Tom Neilson will make a vociferous case to open the presidential debates to Ralph Nader. With the Nader/Gonzalez ticket at about 6 percent in a recent CNN poll, and with an expectation of appearing on the ballot in some 45 states, they certainly have grounds on which to mount an argument. And, just to be clear, let's remember that third party candidates don't ruin elections; they simply enliven the national conversation by removing the either/or-blinders from the eyes public.
