Henry Waxman has defeated John Dingell (from Michigan it should be noted) as the leader of the House Energy and Commerce Committee. Dingell has been the leading Democrat on this committee since, like, Henry Ford was a boy.
Dingell, though a staunch and important Democrat, was no friend of people who wanted high emissions or fuel efficiency standards. Waxman is.
This is a big deal--and signals where the House is headed. Not that I really know about this stuff.
