Was Pigford a failure or a success? If you're a taxpayer you'd almost certainly say it was a failure. As much as $4.4 billion in payouts made mostly to people who had no legitimate claim of discrimination by the USDA. As the NY Times put it, Pigford was "a magnet for fraud."
If you're a left-wing politician who sees government as a machine for transferring money from one group of people to another and benefiting your chances for reelection in the process, then Pigford was arguably a success. I'm talking of course about Barack Obama who pushed for Pigford's extension as a Senator and then gave claimants a "license to raid the till" as President. But the Times also points to Secretary Vilsack and Sen. Menendez as involved in pushing for more payouts. The people who pushed this were progressive Democrats and, prior to the publication of the Times' article this week, there was no downside for these folks. Maybe now, belatedly, there will be.
