It feels odd, but nice, not to hear the overwhelming and excessive coverage of the primaries for these few days between the last set of primaries and Wisconsin coming up in three days. Washington is voting as well but most of the delegates are distributed there via the caucusing which is completed already.
The superdelegate issue now takes front stage as it is extremely unlikely that either Obama or Clinton will go to the convention with enough votes to win. Many superdelegates appears to be holding off on committment, partly because they probably want to go with the winner, and partly because they are concerned about their own political reputations if they pick people that were not in favor in their own district or election territory. Superdelegates are about 20% of the total.
At this stage of the game it appears unlikely that we'll see superdelegates *overturn* the verdict of the popular vote. If Obama continues to perform in future primaries as he has in the last 8 primaries, his vote and delegate totals would be high enough to make if very hard for Clinton to convince superdelegates to vote for her as well as hard to justify a superdelegate win. A more likely scenario however is that Clinton will win in Texas, Pennsylvania, and Ohio, making the total delegate count *so close* that the party will need to do some soul searching to determine how to avoid contention at the Democratic convention.
