Former Democratic Sen. John Edwards, weighing a presidential run in 2008, is wasting little time rallying his party's liberal base. Predicting an electoral "tsunami that starts today and goes to the 2008 election," Edwards said in a conference call with MoveOn house parties at 7 tonight that "We're going to change the country and change the world in the process. The world is going to see the best of this country," he continued, "as opposed to what they've been seeing in the last six years. We're going to get away from being the country of Abu Ghraib and Guantánamo." He also predicted that a Democratic Congress would "move on universal healthcare." A representative of Edwards's political action committee told us that Edwards begins a book tour next week for a tome that was inspired by a trip back to his childhood home in South Carolina; that's one of the first states to vote in 2008's Democratic primaries.
