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.
Right of foreigners to vote in the United States
Historically, over 40 states or territories, including colonies before the Declaration of Independence, have at some time given at least some aliens voting rights in some or all elections. For example, in 1875, the Supreme Court in "Minor v. Happersett" noted that "citizenship has not in all cases been made a condition precedent to the enjoyment of the right of suffrage. Thus, in Missouri, persons of foreign birth, who have declared their intention to become citizens of the United States, may under certain circumstances vote."
