Lots of readers have written in asking about the delegate count between Obama and Hillary. The process of delegate selection and allocation is byzantine at best, in both parties, so there's no one definitive count of how many delegates each candidate can claim at this point in the primary season. (That alone should be a red flag raising doubts about how presidential nominees are selected, but we can save that for another day.)

Eric Kleefeld has compiled the estimates put together by the various news networks of how many delegates each candidate has won on the Democratic side. The estimates vary widely, depending on the methodology used. Looking through them, the only hard conclusion you can draw is that the race remains close with neither candidate a lock to secure the nomination. But for you numbers junkies, it's worth a look.
