Vote Splitting and the First-Past-The-Post System
The FPTP system, employed in various countries including the United Kingdom, declares the candidate with the plurality of votes the winner, even without an absolute majority. This can result in vote splitting, where multiple candidates with similar platforms divide the support base, potentially enabling a candidate with a distinct platform to win with less than majority support. The AV system seeks to rectify this by allowing voters to rank multiple candidates, thereby reducing the impact of vote splitting on the final election outcome.Campaign Dynamics under the Alternative Vote System
The AV system promotes a less adversarial style of campaigning, as candidates must seek not only the first-preference votes but also the subsequent preferences of voters whose first choices are other candidates. This requirement for a broader appeal can lead to more inclusive and less negative campaigning. Studies indicate that the AV system tends to disadvantage candidates with extreme or polarizing positions, as they are less likely to receive the necessary second or third-preference votes to survive the elimination rounds.Benefits of the Alternative Vote System
The AV system offers numerous advantages. It encourages candidates to engage with a wider electorate and generally favors those with moderate views over extremists. Negative campaigning is less effective, and voters can confidently vote for their preferred candidate without the fear of "wasting" their vote, as their subsequent preferences will come into play if their top choice is eliminated. Moreover, the AV system helps to ensure that the elected candidate is one that a majority of voters can support, which advocates argue enhances the democratic nature of elections.Criticisms of the Alternative Vote System
However, the AV system is not without its criticisms. It is not a proportional representation system and can sometimes produce results that are more disproportionate than those under FPTP. The complexity of the system may discourage some voters from participating, and there is a risk of "donkey voting," where voters rank candidates in the order they appear on the ballot without consideration. The AV system can also lead to the election of a "compromise" candidate who is not the most favored but the least objectionable. Furthermore, the counting process is more labor-intensive and time-consuming, and the transition to AV-compatible voting technology can incur significant costs.The Alternative Vote in Australian Elections
Australia serves as a key example of the AV system in practice, having implemented it in 1918 to prevent vote-splitting among conservative candidates. The system is utilized in both federal and state elections, with some states mandating full preferential voting (FPV), where voters must rank all candidates, and others permitting optional preferential voting (OPV), where voters can rank as many or as few candidates as they wish. The use of preferential voting has reduced the dominance of a two-party system and has allowed minor parties to exert greater influence in Australian politics.The Alternative Vote Referendum in the United Kingdom
In the United Kingdom, the AV system was the subject of a 2011 referendum following the coalition government formed between the Conservative Party and the Liberal Democrats after the 2010 general election. Although the Conservatives had historically been resistant to electoral reform, they consented to the referendum as part of the coalition agreement. The proposition to adopt the AV system for elections to the House of Commons was decisively rejected by approximately 68% of voters. Nonetheless, the AV system is employed by the Labour Party and the Liberal Democrats for the selection of their party leaders.
