So in the scuffle that was the Democratic Presidential Debate last night Clinton and Obama exchanged a number of accusations including that Clinton served on the board of directors of Wal-Mart; Obama worked for a law firm that represented an inner-city slumlord. Whether or not those barbs are accurate, in good taste, or relevant has generated a lot of media coverage. But the accusations that really caught my attention were the references both Clinton and Obama made to their opponent's service with "corporate law firms."
