Q: In the 2004 Democratic presidential primaries, John Kerry defeated several Democratic rivals, including Sen. John Edwards (D-North Carolina.), former Vermont Governor Howard Dean and retired Army General Wesley Clark. His victory in the Iowa caucuses is widely believed to be the tipping point where Kerry revived his sagging campaign in New Hampshire and the February 3, 2004, primary states like Arizona, South Carolina and New Mexico. Kerry then went on to win landslide victories in Nevada and Wisconsin. Kerry thus won the Democratic nomination to run for President of the United States against incumbent George W. Bush. On July 6, 2004, he announced his selection of John Edwards as his running mate. Democratic strategist Bob Shrum, who was Kerry's 2004 campaign adviser, wrote an article in Time magazine claiming that after the election, Kerry had said that he wished he'd never picked Edwards, and that the two have since stopped speaking to each other. In a subsequent appearance on ABC's This Week, Kerry refused to respond to Shrum's allegation, calling it a "ridiculous waste of time."
