Nonetheless, there is evidence to support the argument that predictable election results—where one vote is not seen to be able to make a difference—have resulted in lower turnouts, such as Bill Clinton's 1996 re-election (which featured the lowest voter turnout in the United States since 1924), the United Kingdom general election of 2001, and the 2005 Spanish referendum on the European Constitution; all of these elections produced decisive results on a low turnout.
