This couldn't be going any better. Hillary Clinton last night won primaries in Ohio and Texas, reviving her sagging campaign after losing 11 straight states (oh, she also won Rhode Island). While Obama still leads in the all-important delegate count, her wins here are incredibly important. She now has an important claim to use with the superdelegates: She has won California, New York, Texas and Ohio (plus Florida and Michigan, if you want to count it), meaning she's won all of the eight most populous states except Obama's home state of Illinois. Going into Pennsylvania, she's also won the major states that surround it: New York, New Jersey and Ohio.
Keep watching kids, this is going to get really ugly. With Clinton's wins, she isn't going away until the convention. There will be hard-fought battles over the superdelegates, and there will be a war over seating Florida and Michigan (and in a recent CNN poll, over 50% of the people think they should be - despite the agreement between Clinton and Obama that they wouldn't be).
