allow for blank ballots, but voting systems could also add a 'none of the above' option to each race so as to provide multiple clear ways for voters to refrain from speaking/voting if, for some reason, a voter does not want to submit a partially or fully blank ballot. Religious objection is one that many Christadelphians and Jehovah's witnesses, for example, cite as for why they should not participate in political events. As a result, many countries allow religious beliefs as a valid excuse for not going to the polls. Concerns that policies can't address Libertarians in particular debate to what extent voting is a civic duty and not just a civic right. Even in the case of the US where most Americans do see voting as a civic duty, most Americans in a 2020 poll did not like the idea of imposing a $20 fine on those who did not cite an excuse for not voting including a conscientious objection. Research A study of a Swiss canton where compulsory voting was enforced found that compulsory voting significantly increased electoral support for leftist policy positions in referendums by up to 20 percentage points. Another study found that the effects of universal turnout in the United States would likely be small in national elections, but that universal turnout could matter in close elections, such as the presidential elections of 2000 and 2004. In the United States, Democrats would most likely fare better under universal voting (as nonvoters are generally more Democratic) but due to the dearth of close races in the United States, universal voting would change "very few election outcomes." Research on compulsory voting in Australia found that it increased the vote shares and seat shares of the Australian Labor Party by 7 to 10 percentage points and led to greater pension spending at the national level. While weakly enforced compulsory voting in Austria increased overall turnout by roughly 10 percentage points, there is "no evidence that this change in turnout affected government spending patterns (in levels or composition) or electoral outcomes." A 2016 study finds that compulsory voting reduces the gender gap in electoral engagement in several ways. A 2016 study of the Netherlands found that the abolition of compulsory voting increased the vote share of Dutch social democratic parties while reducing the vote share of "minor and extreme parties." Research suggests that higher rates of voter turnout lead
