Huge news. Great news. Michigan Representative John Dingell, who has spent over 50 years in the House of Representatives being the auto industry's babysitter, has lost his position as chairman of the House Energy and Commerce Committee to the younger and more liberal Henry Waxman. The House Democratic caucus voted by secret ballot this morning. Members had a choice between voting for seniority or the possibility of bold and necessary action on climate change. They made the right choice, 137-122.
