Several nations have forms of compulsory voting, with various degrees of enforcement. Proponents argue that this increases the legitimacy—and thus also popular acceptance—of the elections and ensures political participation by all those affected by the political process and reduces the costs associated with encouraging voting. Arguments against include restriction of freedom, economic costs of enforcement, increased number of invalid and blank votes and random voting.
