A concise description of it, over at Ann Althouse’ site (see second comment):

Obama would not be getting the super delegates at this stage if he were not african american.

Hillary has the popular vote. Moreover, if primaries were held again today, Hillary would greatly expand her lead. She would beat Obama by 3/4 of a million votes in Florida and she would crush him in Michigan. In addition, Obama’s big lead from Illinois would shrink.

Today compared to January, what we know about Hillary has not changed. This is not true for Obama. Everything we have learned about Obama in March-May has been negative. The truth is that Obama was unknown on Super Tuesday and people voted for him because they thought he was something other than what he is. Today Obama is more known and the trend of support for him in the battleground states is downward. The super delegates were put in place to pick up on these trends. Unfortuantely, the race issue has tied their hands.

Oh, well. Sux to be them.

It’s a bed they made, though. Sleep tight.
