With a bit of momentum from her landslide Kentucky victory and less lopsided Oregon loss, Hillary Clinton is turning her attention to two states that have already voted, Florida and Michigan, over two states and a territory that have yet to, South Dakota, Montana and Puerto Rico. It's part of a last-gasp strategy aimed at prolonging her campaign by convincing the party to alter the nomination math. By seating the penalized Florida and Michigan delegations, she would not only gain a significant number of delegates but also bolster her popular vote argument with the superdelegates. The new Florida and Michigan offensive will kick off in earnest today with three campaign events in South Florida though she'll have to share the state with Obama, who begins a three-day campaign swing there and will likely also include campaigning in Michigan.
