Opinions on Gorbachev are deeply divided. According to a 2017 survey carried out by the independent institute Levada Center, 46% of Russians citizens have a negative opinion towards Gorbachev, 30% are indifferent, while only 15% have a positive opinion. Many, particularly in Western countries, see him as the greatest statesman of the second half of the twentieth century. U.S. press referred to the presence of "Gorbymania" in Western countries during the late 1980s and early 1990s, as represented by large crowds that turned out to greet his visits, with "Time" magazine naming him its "Man of the Decade" in the 1980s. In the Soviet Union itself, opinion polls indicated that Gorbachev was the most popular politician from 1985 through to late 1989. For his domestic supporters, Gorbachev was seen as a reformer trying to modernise the Soviet Union, and to build a form of democratic socialism. Taubman characterized Gorbachev as "a visionary who changed his country and the world—though neither as much as he wished." Taubman regarded Gorbachev as being "exceptional... as a Russian ruler and a world statesman", highlighting that he avoided the "traditional, authoritarian, anti-Western norm" of both predecessors like Brezhnev and successors like Putin. McCauley thought that in allowing the Soviet Union to move away from Marxism–Leninism, Gorbachev gave the Soviet people "something precious, the right to think and manage their lives for themselves", with all the uncertainty and risk that that entailed.
