Bork responded, "There was not a line in that speech that was accurate." In an obituary of Kennedy, "The Economist" remarked that Bork may well have been correct, "but it worked." Bork also contended in his best-selling book, "The Tempting of America", that the brief prepared for Senator Joe Biden, head of the Senate Judiciary Committee, "so thoroughly misrepresented a plain record that it easily qualifies as world class in the category of scurrility." Opponents of Bork's nomination found the arguments against him justified claiming that Bork believed the Civil Rights Act was unconstitutional, and he supported poll taxes, literacy tests for voting, mandated school prayer, and sterilization as a requirement for a job, while opposing free speech rights for non-political speech and privacy rights for gay conduct. However, in 1988, an analysis published in "The Western Political Quarterly" of "amicus curiae" briefs filed by U.S. Solicitors General during the Warren and Burger Courts found that during Bork's tenure in the position during the Nixon and Ford Administrations (1973-1977), Bork took liberal positions in the aggregate as often as Thurgood Marshall did during the Johnson Administration (1965-1967) and more often than Wade H. McCree did during the Carter Administration (1977-1981), in part because Bork filed briefs in favor of the litigants in civil rights cases 75 percent of the time (contradicting a previous review of his civil rights record published in 1983).
