Jonathan Alter: After Kentucky and Oregon, Barack Obama has an official popular vote lead of 449,486.This does not include Iowa, Nevada, Maine (where Obama won easily) or Washington state. Why? Because these caucus states don't officially report their popular votes. But if we're going to truly count all the votes, official and nonofficial, as Hillary Clinton advocates, you can't very well not include caucus states. Adding in the unofficial tally from caucus states, as estimated by realclearpolitics.com based on official caucus turnout and the number of local delegates selected at the precinct level, that gives Obama a lead of 559,708.
