I always like reminding people of this, cause a surprising number don't realize it. But based on both Wikipedia and Dave Leip's numbers, Hillary Clinton actually BEAT Barack Obama in the '08 Democratic primary POPULAR VOTE. DNC rules dictate that of course, delegates, and not the actual number of votes a candidate receives, is what determines the winner of the primary. But still, it's not insignificant to note that Obama got the Democratic nomination while receiving LESS votes than his opponent.
Well tbf that was because of Michigan and Florida.
