Howard Dean was at the top of the polls in Iowa leading up to the 2004 Iowa Caucuses. Richard Gephardt was polling well, but trending down. Gephardt had placed all his bets on Iowa and had to find a way to win. So Gephardt started running ads going after Dean. Dean countered back with ads attacking Gephardt. While Gephardt's and Dean's ads turned Iowans off from their campaigns, John Kerry and John Edwards kept focusing on the issues and organizing. ... After this week's spat between Hillary Clinton and Barack Obama, I can see this scenario happening again. ... There is a good chance Clinton and Obama will do exactly what Dean and Gephardt did and we will see yet another murder-suicide scenario.
