Another candidate has stepped into the presidential race. Ralph Nader announced on Sunday he's launching a third-party campaign for the White House. Nader tells NBC's "Meet the Press" most people are dissatisfied with the Democrats and the Republicans over the Iraq War and the economy.
Nader says John McCain, Barack Obama, and Hillary Clinton have all failed to support full Medicare for all, and aren't willing to crack down on Pentagon waste.
Nader also ran as a third-party candidate in the 2000 and 2004 presidential elections.
