They'll canvas like mad, don't get me wrong, been getting that crap through my letterbox as well. What's really interesting though is how that go vote propaganda has really fallen off a cliff and it's almost certainly because even the elites have realised a good chunk of the non-voters are going to be making up the people who vote the other way. I don't know how it is in America, but it's been interesting seeing the stats finally coming in with the vote turn out being higher than ever and all of a sudden Le Pen is in the lead lulz.
It used to be something of a fixture in western democracies back in the day with politicians sometimes even floating the idea of mandatory voting like in Australia which is cancer.
The most ridiculous thing though is that only two levels of government have compulsory voting, not the local government level - and that is where most of the bullshit starts, at grassroots levels like Drag Story Time. So, I would actually like to see compulsory voting at that level but not at the federal level. Honestly, in this day and age in Australia, everyone has to have a MyGov account for government services, so there's really no need for actual polling booths - they could just do the whole thing through MyGov and save millions of dollars. And then the voting could be audited for Shenanigans; Which is probably the real reason they don't do it.
Online voting is an incredibly bad idea. For one thing, it makes electoral fraud at scale way easier - no longer needing boots on the ground means you can flip elections even in deep red areas from the comfort of Google HQ. And the kind of audit you're talking about, where you can associate individual votes with individual voters and persecute them for it - is exactly what the secret ballot is meant to prevent.
