The more disengaged, the less likely that political parties will believe that a vote will be cast and therefore will seek a response from those in marginal seats who they are almost certain will vote.
People who have a strong sense of political efficacy feel that they have the skills and resources to participate effectively in politics and that the government will be responsive to their efforts. Those who believe in the legitimacy of the political system and are highly efficacious are more likely to participate in politics and to take strong stands on public-policy issues.
