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.
Exhaustive ballot
Because voters may have to cast votes several times, the exhaustive ballot is not used in large-scale public elections. Instead it is usually used in elections involving, at most, a few hundred voters, such as the election of a prime minister or the presiding officer of an assembly. The exhaustive ballot is currently used, in different forms, to elect the members of the Swiss Federal Council, the First Minister of Scotland, the President of the European Parliament, and the speakers of the House of Commons of Canada, the British House of Commons and the Scottish Parliament, the various party nominees for President of the United States, the host city of the Olympic Games and the host of the FIFA World Cup, and, formerly, to elect the President and the State Comptroller of Israel, which are now elected – though still indirectly by the Knesset – using a two-round system.
