The Chesapeake and Potomac primaries were certainly good to Barack last night. He didn't just win in the District of Columbia, Maryland and Virginia primaries. He dominated.
He's favored in Wisconsin and his native Hawaii next week (there's also a non-binding primary in Washington state, where he's already had a caucus victory). My vote may have gone to Hillary when Tennessee's primary was held, but my hope (wishful thinking though it may be) is that Hillary "suspends" her campaign if she loses those and the Texas and Ohio primaries on March 4 (Vermont and Rhode Island vote that day too). Despite her earlier victories in such states as California and New York, the momentum Barack has now is pretty impressive; the momentum he'd have if he continues his winning ways into March would be so strong that contesting the matter further would be divisive.
