Potomac Potentas?

Fantastic weekend for the junior senator from Illinois. He swept small but nevertheless influential caucuses and primaries across the board and decreased Hillary's delegate lead to a mere 27 according to CNN.

The upcoming Potomac Primaries tomorrow will be huge. Split voting will keep the race tight; Hillary could make a stand and reverse Obama's recent trend; victories by Obama would further enhance his burgeoning status as Candidate of the Hour. Conventional wisdom seems to hold that Obama has the edge in Virginia, Maryland and the District of Columbia. Josh Patashnik says that this isn't necessarily the case, and makes a good argument as to why that is.
