This delegate counter obviously isn't counting the RELOVEUTION or whatever you young'uns are calling it. Everyone knows that Ron Paul will win all of the delegates, but the establishment is just using an elaborate ruse to trick us.
Being serious here: NYTimes uses the AP guesstimates, which are determined by a few people at the AP saying stuff like, "Since Romney got 70% of the vote, he gets 70% of the delegates." It don't work that way, as we've seen in North Dakota, Maine, Minnesota, Colorado, Nevada, Iowa, and the Virgin Islands.
