The scourge of superdelegates - Will Franklin graphs out how the political parties split up their delegates. Republican superdelegates comprise 6% of all delegates but Democratic superdelegates add up to 20% of all delegates, a sum equal to all the delegates in Iowa, New Hampshire, South Carolina, Nevada, California, and Illinois, combined.

If Clinton and Obama head into the Democratic National Convention and Obama has a lead in "regular" voting delegates (as he does now), there's going to be some bitter internecine warfare if party officials cut a back-door deal with the Clintons.
