Last I ran the numbers (using my own spreadsheet built with data from MSNBC), this was the breakdown of the Super Tuesday popular vote:
Clinton 7,435,435 Obama 7,390,600 Edwards 412,556
I'm including Edwards in there because California, which has a disproportionately large number of mail-in ballot voters, also had an atypically large number of Edwards voters -- a little over 4%, compared to about 2% everywhere else.
Based on some back of the envelope calculations, I'm figuring that about 70% of the Edwards people have gone to Obama, and about 25% to Hillary.
Thus, almost all of the gap between Hillary and Obama probably would have been made up by Edwards voters.
Excluding Michigan, the overall popular vote so far (imputing Nevada and Iowa caucus goers based on state delegate breakdowns):
Clinton 8,674,768 Obama 8,501,311
Excluding Florida as well:
Clinton 7,817,560 Obama 7,932,270
Effectively, to the extent that Hillary has a popular vote lead it is on the basis of Florida.
I don't know what to make of that, but at least Florida wasn't like Michigan where Hillary's name was the only one on the ballot.
