That same day the GOP amendment failed, the derivatives expert Adam White was at his home in Georgia, poring over a "redline" version of the Lincoln amendment, in which changes to the bill are tracked in bold. When he came to a key passage on page 570, he saw that it had a single line through it, meaning it had been removed. The line read, "Except as provided in paragraph (3), it shall be unlawful to enter into a swap that is required to be cleared unless such swap shall be submitted for clearing."
Translation: It was no longer illegal to trade many uncleared swaps. Wall Street would be free to go on trading these monstrosities by the gazillions, largely in the dark. "Regulators can't say any longer if you don't clear it, it's illegal," says White.
Once he noticed that giant loophole, White went back and found a host of other curlicues in the text that collectively cut the balls out of the Lincoln amendment.
