I have updated my estimates of the popular vote including caucuses to include Mississippi.  For background and an explanation of methods and data see my previous post at http://tpmcafe.talkingpointsmemo.com/talk/2008/03/popular-vote-estimates-includi-1.php

The updated results are:

Total without Michigan and Florida
Clinton 12,803,453 (46.5%)
Obama 13,609,562 (49.5%)
Obama lead 806,109

Total with Florida but not Michigan
Clinton 13,674,439 (46.7%)
Obama 14,185,776 (48.5%)
Obama lead 511,337

Total including Florida and Michigan
Clinton 14,002,748 (46.9%)
Obama 14,345,636 (48.1%)
Obama lead 342,888

Here is the breakdown of primaries versus caucuses. I am only showing the results without Florida and Michigan, but you can easily calculate the primary results for the other versions by simply subtracting the caucus results from the totals above.
