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.
Disfranchisement
In some countries, such as China and Portugal, disfranchisement due to criminal conviction is an exception, meted out separately in a particular sentence. Losing voting rights is usually imposed on a person convicted of a crime against the state (see civil death) or one related to election or public office.
