Even then, the repeal bill passed 221–203 in the House, but the two-thirds majority it needed in the Senate was never attained, partly because of long filibustering by Republicans such as Minority leader Everett Dirksen.
即使在当时，废除法案以221-203票在众议院得以通过，但在参议院该废除法案从未以規定的2/3多数票通过，部分原因是废除法案的推行受到如少数黨领袖埃弗雷特·德克森等共和党員的长期阻挠。
