MATTHEWS: I‘m not sure. David Corn, I want to ask you this question: Why is it that all the liberals we know, every liberal we know was thrilled that this country was capable of electing an African American president?

They were not thrilled by the idea that this country was capable getting beyond its race past—it‘s racial past, not racist, but racial past.
Why is it that liberals liked that idea and conservatives didn‘t like were not thrilled by it? They just didn‘t have the same reaction.
