Carter also attempted to break one of the last mass strikes of the 1970s, that by the United Mine Workers, by invoking the Taft-Hartley Act. The striking miners ignored the president and adopted the slogan “Taft can mine it, Hartley can haul it, and Carter can shove it.” 25 The neoliberal agenda, however, rolled on as the Joint Economic Committee of Congress, with a Democratic majority and the endorsement of the liberal’s liberal Ted Kennedy, reported in 1979 “that the major challenges today and for the foresee- able future are on the supply-side of the economy.” 26 For the Democrats, the Keynesian foundation of post–World War II liberalism was a thing of the past. As Paul Heideman put it in his analysis of the realignment strategy in Jacobin, “The window for realignment had closed.” 27 As loyal Democrats, however, Harrington and the realigners went on to support Carter in 1980 once Ted Kennedy’s primary challenge was defeated, and Walter Mondale in 1984 as the party moved to the right.
