- Obama leads in pledged primary/caucus delegates but,- Clinton leads in the popular vote of Democratic primary voters- Obama has won more (mostly small) states but,- Clinton has won the lion's share of big electoral vote rich states- Neither candidate has enough pledged delegates to win without the superdelegates but,- Clinton will have won Florida's first primary (even if it doesn't count) and the perception is that Clinton would win a re-vote in Florida where she has always been strong and in Michigan where the economy (her sweet-spot with low income voters) is the key issue.- and Clinton has the last burst of momentum at the time when superdelegates must decide.
