This count shows Senator Clinton ahead in the popular vote because a caucus is, by definition, not a "popular vote".  To lump them together is apples and oranges.  

As of today, with yesterday's Potomac primaries included, here are the totals for the last two Democrats left standing:

Clinton: 9,594,849
Obama: 9,513,482

Clinton's popular-vote margin is 81,367, a difference of about four-tenths of one per cent.

I won't comment on the numbers of votes or delegates - I have simply seen so many different counts of both that it is hard to decide what's the truth.

But here is another proof of Obama's potential to reach out to independents and even republicans: a McCain advisor that will step back from the campaign if the final opponent in the general election is Obama.

Has anyone heard much about the Republican vote for Obama? It seems strange that Democratic Primary turnout came close to Kerry's 2004 General election vote and also surpassed Republican turnout in heavy Republican jurisdictions - especially in the Valley.  I've heard of 8 Republicans who voted in the Dem primary against Hillary. Half said they would vote for McCain in the fall and the others said they wouldn't vote, let the Dems screw it up for 4 years then take it back with someone more to their liking than McCain who they hate almost as much as Hillary.  
Not bad news for Obama, just interesting how the mix is on the Republican side and the Hillary effect. Actually good news if a lot of this holds in the fall depending who the Dem is.  R's staying home hurts the Congressional R's.
