The classic account of how the Equal Rights Amendment failed, and what that means for democratic politics and equality. In March 1972 the Equal Rights Amendment to the United States Constitution-the ERA-passed the Senate of the United States with a vote of 84 to 8, seventeen votes more than the two-thirds required for constitutional amendments. In the ensuing ten years, a majority of Americans consistently told interviewers that they favored this amendment to the Constitution. Yet on June 30, 1982, the deadline for ratifying the amendment passed with only thirty-five of the required thirty-eight states having ratified. How did this happen? In How We Lost the ERA, political scientist Jane J. Mansbridge tells the story of the ERA's rise and fall, revealing self-defeating, contradictory forces within the movement supporting the amendment and how those contributed to its demise. The surprising challenges Mansbridge uncovers here remain salient to political struggles and democratic theory today.
