Barack Obama would have wrapped up the nomination weeks ago. He took over 90% of African American voters who make up a third of the electorate in securing his apparently comfortable win. In Indiana Hillary Clinton is leading by a healthy margin, but the race is not yet called. Did Obama make progress with whites, women, seniors, rural voters – any one not in his core group of African Americans and young voters? No, accordingly to available exits (which are reweighted as real votes come in.)

So do superdelegates feel comfortable with a candidate who continues to maintain his delegate lead but is unattractive to key groups and is losing appeal with Republicans and independents? If they don’t they aren’t saying, and there is little they can do about it, absent further wins or new troubling information about Obama. The Democrats may have their nominee soon, but he may not be what they hoped for when the bulk of those votes were cast months ago.
