With recent Congressional wins for the Democrats, the number of superdelegates has changed and it will now take 2,026 instead of 2,025 delegates to win the nomination at the Democratic National Convention in Denver in August (details will be here eventually; at last check it still had the April numbers)

So reset your calculators. And be ready to reset them again depending on what the DNC rules committee decides in a couple of weeks. And you serious junkies can always spend a little time on the delegate tracker. It's not as cool as that interactive map that John King plays with on CNN, but it will let you play analyst from the comfort of your own home -- or work cubicle. And we have to wonder -- on nights when Barack Obama can't sleep, do you think he dozes off by counting delegates?
