Last night saw results from Indiana and North Carolina and in the end, Obama gained another 12 delegates over Clinton. She won a narrow victory in Indiana, a largely white state, with a two point lead in votes and 4 more delegates than Obama. He won convincingly in North Carolina, with a twelve point lead in votes and 16 more delegates. His victory comes after the Wright debacle and the gasoline tax debate (she wants to ease taxes over the summer and he doesn't, arguing that its a band aid solution that won't solve anything).
So it all grinds on. He has extended his lead; she's still fighting until the convention. The Clinton camp is now arguing even more strenuously for the seating of Michigan and Florida, and that will be settled on the 31st.
