Obama, in particular, is the one candidate was a narrative for his candidacy -- ending the culture of corruption that plagues Washington D.C. I hope voters in Iowa, where the nomination is likely to be decided, realize that Obama, unlike Edwards, who's taken a sharp leftward turn, is the only electable Democrat who understands that the White House doesn't need just a change of parties, it needs a change of values. Obama will help us break free from the other Washington consensus, the one in which lobbyists and politicians work together to block progress on the issues of the day.
