All the people saying mandatory voting is bad are misinformed. It is essential for democracy, and should be applied everywhere.
Australia has mandatory voter turnout, but you do not need to submit a vote. You just need to show up on polling day.
Everyone has political interests and needs to be politically represented, but some people are too tired after work to take themselves to the polling centre. Others are incarcerated. If anything, those people are more in need of political representatives.
American conservatives spend billions trying to prevent poor overworked people from reaching polling places or exercising their right to vote. Mandatory voting prevents that.
Make no mistake, Australian democracy is healtheir than whatever clusterfuck in going on in the US.
Some would ask, how could a perfect God create a universe filled with so much that is evil. They have missed a greater conundrum: why would a perfect God create a universe at all?
