Fair warning. I am about to speak very ill of the dead. David Koch went to his eternal barbecue spit on Friday. Except for his surviving brother, Charles, no man had a worse effect on American politics since the death of John C. Calhoun. Every malignancy currently afflicting us can be traced in one way or another into their wallets, and that's not even to mention the lasting damage they've done to the planet as a whole. Sorry, Morning Joe gang, I wouldn't care if they opened branches of the National Museum of Puppies and Rainbows in every congressional district in the United States. The Koch brothers financed the wrecking ball that is still doing damage, and now one of them is dead, and, if I am not rejoicing, I am breathing deep sighs of relief and praying deep prayers of thanksgiving.
