I believe you without looking it up. It is becoming common knowledge that his strength is in 3 areas: youth - especially college students, African-Americans, and red state Independents.
On Tuesday he racked up many delegates on the basis of his support from red state independents in the mountain west. These are people who have never liked either Clinton and were happy to vote against Hillary. She knew they were a lost cause form the start and barely contested these states. Obama's success in these states is no indication that he would win them in November - he is not popular among the white Republicans that dominate those states, or the right-leaning Independents who would vote for McCain.
Bottom line is that there is not one red state that Obama can get that Hillary cannot. In fact, she could get Florida and Arkansas where he could not. These are the considerations that super-delegates will have.
Even Obama himself looked bored with his speech Tuesday night. He needs some new material. Repeated exposure to the same speeches results in diminishing returns.
And the Rezko stuff is only going to heat up in the next few weeks as witnesses are cutting deals with the prosecutors. Obama has yet to provide a credible answer about his real-estate dealings with Rezko. Are we supposed to beleive he and Michelle, two extremely intelligent people, need Reskos help to buy their own home?
Tuesday night I saw one candidate who looked like she had won the night, and another who looked disappointed. Now I see one who is willing to engage and debate and one who is not. The media is going to fall out of love with this guy real fast.
