Excellent diary over at Daily Kos by PocketNines explaining three important reasons why the popular vote total while interesting is not relevant to the nomination battle:
Point Number 1: If the popular vote determined the nominee, no candidate would ever go to Iowa or New Hampshire. They'd spend all their time in big urban areas all over the country from the outset of the campaign, racking up raw numbers. What would be the point of even visiting New Hampshire if you could camp out in Brooklyn? Concrete Example: Barack Obama would not have spent only a day and a half in California before the Feb 5 primary. He would have never gone to Idaho. Duh.
Point Number 2: If the popular vote determined the nominee, no state in its right mind would ever hold a caucus, instantly disenfranchising itself. Concrete example: Minnesota-Missouri. Minnesota gets credit for 214K votes, and Missouri gets 822K votes, but they each get 72 delegates. Is Missouri's voice 4 times more important than Minnesota's?
Point Number 3: The arbitrary distinction between who gets to vote in these primaries is nothing like the general election, where everyone registered gets to vote. In the primaries, sometimes it's just Dems, sometimes Dems and Indies, sometimes anyone. Concrete example: Texas gets a million more votes than similar overall population New York (2.8M to 1.8M), even though New York is far more Democratic, simply due to this arbitrary restriction on who can vote (NY = closed, Texas = open).
