So, Ralph Nader is once again launching his own third-party presidential candidacy.
Nader tells NBC's "Meet the Press" that most people are dissatisfied with the Democrats and the Republicans over the Iraq war and the economy.
He also says John McCain, Barack Obama and Hillary Rodham Clinton have all failed to support full Medicare for all, and aren't willing to crack down on Pentagon waste.
He says it's the fault of corporate lobbyists and special interests, and that he'll only take donations from individuals.
Nader also ran as a third-party candidate in 2004 and in 2000. Many Democrats still haven't forgiven him for his 2000 race, in which they say he took enough votes away from Al Gore to cost Gore the election against George W. Bush.
Nader won 2.7 percent of the national vote in 2000, but just three-tenths of one percent in 2004.
