What source should be most useful for a student writing a paper that argues that Americans should be fined if they do not vote?

A student writing a paper advocating for fines for non-voting Americans would find academic articles on civic duty and voter participation particularly useful. Research studies examining the effects of financial penalties on voter turnout, as well as analyses of similar policies in other countries, can provide empirical evidence to support the argument. Additionally, legal frameworks regarding mandatory voting and its implications could also serve as valuable sources. Government reports and statistics on voter turnout trends would further strengthen the paper's claims.
