Do a wikipedia search on it-I'd link but Andatech's dynamite linker seems to be fubared today. Quite a few countries have this-lots don't enforce it, but some major democracies do, like Australia.
I'm undecided about this-I think voting is a social obligation in a democracy, as well as a privilege, but I can understand the impediment to civil liberties argument. No way such a system would decrease our flood of political commercials.
How about a penalty for not voting, as you are acting as a lesser citizen/freeloader then. Maybe a xx% discount (or fixed amount discount) on federal taxes for those who do vote & you claim it just like you claim your exemptions? Lie on the tax return and it's tax fraud-and easily checked against the voter rolls in an audit.
How is this enforced in Australia?
Do they put people in jail/prision who refuse to vote?
Do they fine them $1,000 dollars?
What is the repercussion? or did they just put "voting is mandatory" on the books without mentioning any punishment for violators?
Has compulsory voting proven to work? Does Australia have a 100% voter turnout? If not, then I assume the remaining people who didn't vote were either fined or put in prison?
Your idea would be impossible to enforce.
What if the voter only answers one ballot question of the 25 or so questions/votes of candidates on the list?
What if the voter bubbles all the ovals?
What if the voter answered "None of the Above" to every question?
What if the voter didn't answer any questions but there are pencil marks all over the ballot which is not enough to signify voter intent?
What if the voter voted in the primary, but not the general election?
What if the voter votes for local council elections but chooses not to participate in(or skips entirely over federal and state candidates running for office on the same ballot?
What if the voter is unemployed and therefore won't be able to receive your XX% discount on income tax?
What if the person is a college student who his parents claim him as dependent on their taxes meaning he doesn't have to file anything with the IRS? Would the XX% discount(or fixed amount) be awarded to the parents who filed taxes or the student?
What if the person was in a Surgical ICU unit for a month and didn't get the chance to vote?
