Political scientist: People become unenthusiastic about voting if they believe that important problems can be addressed only by large numbers of people drastically changing their attitudes and that such attitudinal changes generally do not result from government action
The decreasing voter turnout is thus entirely due to a growing conviction that politicians cannot solve the most important problems
infers that important problems can be seriously addressed if people's attitudes do change from the premise that these problems cannot be addressed if people's attitudes do not change
