Updating the numbers, which keep on getting better...and better

Over at ObamaIsWinning.com, I've posted an update to the Magic Number Tracker. Barack Obama is now just 216 delegates away from securing a majority of pledged delegates. As long as he wins 38% of the remaining delegates, he'll go to Denver as the only candidate with a legitimate claim to the nomination.

To put 38% in perspective, Barack Obama has won at least 38% of the delegates in all but three states -- Iowa, Arkansas, and Oklahoma. Of course in Iowa, it was a three-way race, so there's really only two states where he's fallen short.

Hillary Clinton, on the other hand, must win a whopping 67% of the remaining delegates to get a majority -- and that's not going to happen. To put her challenge in perspective, she's exceed 67% exactly once. In Arkansas.

The only conceivable way she can get the nomination is by overturning the judgment of voters and the results of caucuses and primaries. Now that Republicans are beginning to interfere on her behalf in our primaries, I don't think superdelegates will put much weight on her performance down the stretch, even if she does do well.

Still, by the media's reckoning, Barack Obama is an underdog. That may well be. But he's an underdog that just can't lose.
