There's nothing fuzzy about it. Her name was marked on more ballots than every other candidate in the Democratic primaries. Cutting Florida and Michigan popular votes in half is ignorant. The DNC did NOT cut the votes in half, they cut the delegates' votes in half (and then reinstated them, further nulling the argument). As for the caucus states, those are INCLUDED in RCP's tallies. The guy who wrote your article is an idiot.
RealClearPolitics - 2008 Elections - Democratic Vote Count
Please read the second and third totals. The third total counts Michigan. The fourth total counts Michigan AND the caucus states. Note the asterisks beside these numbers.
Giving Obama all 238,168 of those votes is not only ignorant, it's wrong. John Edwards was still running a strong campaign during this election. Obama would need 176,466 of the 238,168 uncommitted votes to win the overall popular vote. So, for him to beat Clinton in the overall popular vote, you would have to assume that Edwards AND Richardson would receive less than 61,702 votes combined, which I do not believe would have happened. But, I can't assume anything. Statistically, however, Edwards polled around 12% in the
exit polls, which is rougly 67,977 votes.
So, say what you will. The fact remains: her name was marked more than anyone and probably still would have been even if his name was on the Michigan ballot.
