Compulsory voting
Compulsory voting is increasingly resented by citizens in some countries such as Brazil, the largest country where compulsory voting is enforced: at the last presidential election in 2014, some 30 million voters, about 21% of registered voters, did not vote, despite the fact that Brazil has some of the most severe penalties enforced against non voters.
Voter apathy
Voter registration in the United States is an independent responsibility, so citizens choose whether they want to register or not. This led to only 64% of the voting age population being registered to vote in 2016. The United States is one of the sole countries that requires its citizens to register separately from voting. The lack of automatic registration contributes to the issue that there are over a third of eligible citizen in the United States that are not registered to vote.
