It may turn out to be even worse than he thinks. One reason for this bill, paradoxically, was to fix a mistake made the last time lawmakers were in too big a hurry to find out what they were voting for. The tax overhaul passed in December included a provision that became known as “the grain glitch,” giving farmers an ill-considered incentive to sell to agricultural cooperatives rather than grain companies. The spending bill cleaned up that little mess. Future legislation may be required to repent of errors in this bill.
