Voting should be compulsory. You vote or you get a fine like in Australia. Everyone's vote should be equal also, none of this let's give more power to the uneducated.
Anyone who is legitimately interested in compulsory voting should read Compulsory Voting: For and Against by Jason Brennan and Lisa Hill. Of interest to a lot of posters,
"[There is a] widespread belief that ”if everybody in this country voted, the Democrats would be in for the next 100 years." ... [T]his conclusion ... is accepted by almost everyone except a few empirical political scientists. Their analyses of survey data show that no objectively achieved increase in turnout – including compulsory voting – would be a boon to progressive causes or Democratic candidates. Simply put, voters' preferences differ minimally from those of all citizens; outcomes would not change if everyone voted."
(Benjamin Highton and Raymond Wolfinger, ”The Political Implications of Higher Turnout," British Journal of Political Science 31 (1) (2001): 179–223). Also Sarah Birch in here compilation study Full Participation (which reviews nearly all the literature ever written on compulsory voting comes to the same conclusion).
I also think the claim that there is a civic or moral duty to vote is highly dubious (and for what it's worth most academic political philosophers agree with me, even those who consider themselves welfare liberals or what most gaffers would be). It's not clear that we have a duty to vote to others. At best we have a duty to vote well (whatever that means) but the information required to vote well is difficult to attain and not everyone can be sociologists, political scientists, philosophers, etc lest we abandon the division of labor in society. Most ill-informed voters are what economists call rationally irrationally.
Personally I'm against compulsory voting on deontological grounds. As established in West Virginia v Barnette people have the right to not speak. Considering voting is a speech act people have the right not to vote. Note that I claim the right to not vote as an extension of the right to not speak (the corollary to the right to speak). I don't claim there is an independent right not to vote (there may or may not be but that requires extensive work in political philosophy).
That being said if governments want to employ non-coercive means of raising voter turnout I'm ambivalent.
For what it's worth I'm a classical liberal/libertarian political amateur political philosopher going to grad school in the near future to be a professional classical liberal/libertarian political philosopher(Not that that should effect how you assess my arguments). I'm currently doing research on deontological objections to compulsory voting. I also didn't mean to "call you out" your concerns seemed to be a prevailing theme in this thread.
