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 suppression in the United States
The United States is the only democracy in the world that regularly bans large numbers of felons from voting after they have discharged their sentences. Many countries including Canada, Denmark, France, Germany, Israel, Japan, Kenya, Norway, Peru, Sweden, and Zimbabwe allow prisoners to vote (unless convicted of crimes against the electoral system). Some countries, notably the U.K., disenfranchise people for only as long as they are in prison (however, this has been challenged by the European Court of Human Rights).
