As Clinton prepares for victory in W.VA., Obama's prepares victory lap

Democrat Hillary Clinton is expecting a big win in tonight's primary in West Virginia, but it's unlikely to improve her increasingly tenuous position in the presidential race.

While rival Barack Obama continues to stump in the states with upcoming primaries, including South Dakota and Oregon, he's embarking on what looks like a general election tour. Over the next week and a half, he's headed to the battleground state of Missouri -- a state whose primary he won three months ago -- as well as to Michigan and Florida -- states he boycotted in the primary.

Details on his trip to Florida are pending, but are expected to include a mix of private fundraisers and public rallies in central and South Florida. Some pointers for Obama's Florida itinerary are here.
