On the final night of the primary season, Clinton won South Dakota on Tuesday while Obama took Montana — and a slew of party superdelegates who declared their support to help him clinch the nomination. He did it, according to The Associated Press tally, based on primary elections, state Democratic caucuses and support from superdelegates. It took 2,118 delegates to clinch the nomination at the convention, and Obama had 2,154 by the AP count.

So, apparently we're coronating the Democratic nominee on the basis of a source in our famously free press that ran a story on the same day that was wrong, and designed to take Hillary down.

Not to quarrel with the idea that Obama has a majority of the pledged delegates -- though pledges only turn into votes at the convention -- but does anybody have a timeline of when and how Obama actually crossed over to the majority in AP's count?
