After reviewing evidence from Venona and other sources, historian John Earl Haynes concluded that, of 159 people identified on lists used or referenced by McCarthy, evidence was substantial that nine had aided Soviet espionage efforts. He suggested that a majority of those on the lists could legitimately have been considered security risks, but that a substantial minority could not.[117]
These viewpoints are considered revisionist by many scholars.[118] Challenging efforts aimed at the "rehabilitation" of McCarthy, Haynes argues that McCarthy's attempts to "make anti-communism a partisan weapon" actually "threatened [the post-War] anti-Communist consensus", thereby ultimately harming anti-Communist efforts more than helping.[119] William Bennett, former Reagan Administration Secretary of Education, summed up this perspective in his 2007 book America: The Last Best Hope:
The cause of anti-communism, which united millions of Americans and which gained the support of Democrats, Republicans and independents, was undermined by Sen. Joe McCarthy ... McCarthy addressed a real problem: disloyal elements within the U.S. government. But his approach to this real problem was to cause untold grief to the country he claimed to love ... Worst of all, McCarthy besmirched the honorable cause of anti-communism. He discredited legitimate efforts to counter Soviet subversion of American institutions.
