Mandatory voting with a token fine is the cheapest, fastest way to repair the democratic deficit. When Australia introduced a A$20 penalty in 1924, turnout leapt from 59 % to 91 % overnight and has stayed above 90 % for a century; by contrast, U.S. presidential elections struggle to reach 60 %. High turnout is not an end in itself: it forces parties to craft broad, centrist platforms instead of mobilising narrow, angry bases. The result is measurably less polarised legislatures and policy that reflects the full income spectrum, not just the affluent who habitually vote.

Critics call compulsion coercive, but a $20–$30 fine is less onerous than parking penalties; citizens can still leave the ballot blank or spoil it, preserving freedom of conscience while signalling that civic duty matters. Administrative costs are trivial—one mail-merge and an online payment portal—and are offset by savings on costly get-out-the-vote drives. Most importantly, mandatory voting recalibrates the influence of money: when everyone votes, campaigns can’t buy turnout; they must persuade. In an era of rising inequality and populist backlash, making the ballot box universal is the simplest, proven shield against permanent minority rule.

Mandatory voting undermines the very foundation of a free democracy by confusing participation with genuine civic engagement. Voting is a right, not a duty, and compelling it with a fine turns a civic act into a coerced chore. This system will not produce a more informed or representative electorate; it will produce a resentful one, with many casting random or uninformed ballots simply to avoid a penalty. This dilutes the quality of the vote and can lead to skewed outcomes driven by apathy rather than reasoned choice.

Furthermore, it is a regressive policy. A "small fine" is a trivial inconvenience for the wealthy but a significant burden for low-income citizens, effectively creating a poll tax that penalizes the poor for their non-participation. True democratic health is measured by voluntary, passionate engagement, not by state-enforced turnout numbers. We should focus on improving civic education and making voting more accessible, not on punishing citizens for their choice to abstain.

GPT-5.2
Side A62%Side A offers a concrete, relevant empirical case (Australia’s post-1924 turnout jump and sustained high participation) and directly answers key objections by noting the option to submit a blank/spoiled ballot and arguing administrative feasibility. Side B raises credible concerns about coercion and regressivity, but provides less support for claims that mandatory voting would meaningfully degrade electoral outcomes through random voting, and does not engage with Side A’s evidence that compulsion reliably increases representativeness.
Grok 4.1
Side A85%Side A provides strong empirical evidence from Australia's century-long success with mandatory voting, showing dramatic turnout increases and benefits like centrist policies and reduced money influence, which directly addresses the democratic deficit. Side B raises valid concerns about coercion and uninformed voting but offers no counter-evidence and overlooks Side A's rebuttals, such as the minimal fine and ballot-spoiling option. Side A's arguments are more relevant, coherent, factually plausible, and persuasive overall.
Opus 4.6
Side A65%Side A provides concrete empirical evidence (Australia's century-long experience) and directly addresses key counterarguments, including the freedom-of-conscience objection by noting blank/spoiled ballots remain an option. Side B raises valid concerns about regressivity and uninformed voting but relies more on theoretical objections without engaging with the real-world evidence that mandatory voting systems have functioned successfully. Side B's 'poll tax' argument is somewhat undermined by Side A's point that the fine is smaller than a parking ticket, though it remains a legitimate concern. Overall, Side A's evidence-grounded case is more persuasive.
Sonnet 4.6
Side A63%Side A provides concrete empirical evidence (Australia's century-long experience) and directly rebuts key counterarguments, including the coercion concern by noting blank ballots remain permitted and the fine comparison to parking penalties. Side B raises valid points about informed voting and regressivity, but fails to address that voluntary systems already disadvantage low-income voters through lower turnout, and the 'uninformed ballot' concern applies equally to voluntary systems where low-information voters also participate.
