Everything else is electronic so why not voting ? It would be impossible to vote twice.

Multiple voting is one of the weaker excuses for compulsory, anti-democratic voting. I have never heard the urgers using it, so rare is the practice. I reckon online voting would be the best way to fiddle with the system. Old fashioned mail would be better. That's what local government already does. Voluntary, but more convenient if you do wish to vote. Voting by post has increased council votes.

"Multiple voting is one of the weaker excuses for compulsory, anti-democratic voting. I have never heard the urgers using it, so rare is the practice. "

Thanks for that observation, it's because of Compulsory Voting that the practice is rare in Australia.
Under voluntary voting, as is used in Britain, multiple voting or voting in the name of those too lazy to vote is common.
In Northern Ireland, if one died within a week or so of the polls, and depending on the weather, one would be kept on ice (literally for those that could afford it) until the vote could be cast.
"Vote Early, Vote Often" was a war cry for both Republicans and Loyalists.

ttbn,

You said, "Compulsory voting is totally undemocratic"

If that is so then all the other compulsions by law on the citizens are also undemocratic, military service in time of war, taxation, vaccination, paying for passports, motor vehicle registration, council rates etc., etc.

Is Mise,

The things you mention have no similarity to voting. But, you are obviously hell bent on arguing for the sake of arguing, so I'll leave you to it.

ttbn,

"The things you mention have no similarity to voting..."

Quite right and very perceptive of you to notice, however, they do have similarities to Compulsory Voting, they are compulsory and that compulsion is imposed by the State.
