In this blog post, we examine the characteristics and limitations of voting theories to see how they explain voters’ political choices and behavior.
Voting is an act through which voters can express their views on major issues and exercise control over political power; it is the most common form of political participation available to the general public. Consequently, political scientists and election experts have studied voters’ voting behavior in the context of elections. This research generally investigates voters’ voting tendencies—such as their attitudes toward participation or their motivations—to determine how these factors correlate with election outcomes. There are various theories that explain voting behavior, with representative examples including the party-identity model, sociological models, and rational choice models.
The party-identity model views the psychological attachment a voter holds toward a specific political party as the most important factor and uses this to explain voting behavior. Attachment to a political party can be defined as a sense of belonging—that is, a “sense of affiliation with a specific party”—that a voter develops through an internal connection with that party over a long period of time. This sense of belonging is formed within the family under the influence of parents and is considered the most stable and long-lasting political attitude. Furthermore, the party identity model takes into account the various social, cultural, and educational factors that voters experience in the process of forming and maintaining their political identity. For example, a family atmosphere that aligns with a specific party’s policies or ideology, political education received in school, and the political leanings of friends in one’s social circle can all play a significant role in shaping a voter’s sense of party affiliation.
The sociological model views the voter’s social background as the most important factor and uses it to explain voting behavior. This model was particularly prominent in Western Europe, where class, race, religion, and region served as key determinants of party affiliation. Since this model assumes that individuals are inevitably influenced by the social groups and backgrounds to which they belong, it emphasizes that voters with similar social backgrounds tend to exhibit similar voting behavior. The sociological model also analyzes the influence of factors such as a voter’s occupational and economic status on voting behavior. For example, voters from the working class, middle class, and upper class each have different economic interests, which can significantly influence their choice of political party or candidate.
The rational choice model views the individual voter’s self-interest as the most important factor and uses this to explain voting behavior. Since this model views humans as beings who act to maximize their own interests, it regards voting as a means to achieve personal goals. Therefore, it posits that voters select candidates who propose policies that align with their own interests and needs. The rational choice model emphasizes the rational calculations that occur as voters carefully analyze candidates’ pledges and policies and select the candidate most advantageous to them. In this model, how effectively voters collect and process political information becomes a key variable.
However, these models each have their limitations. The party-identity model struggles to explain why voters tend to vote based on individual candidates rather than political parties. This is because, in modern elections, the personal charisma or competence of individual candidates often plays a more significant role than the party itself. Sociological models struggle to explain why voters cast their ballots based on individual autonomy rather than their social background. This is because, in modern society, voters are becoming increasingly individualized and tend to be influenced by personal beliefs and values rather than traditional social factors. Furthermore, the rational choice model struggles to account for the fact that voters cannot be completely free from their social backgrounds. Voters are still influenced by their social status or economic background, and it is often difficult for them to make completely objective and rational choices.
Nevertheless, since voting is one of the sources that provides rich information about the interactions between individuals, society, and politics, research on voting behavior remains valuable.
Such research plays a crucial role in understanding how voters’ voices are reflected in political institutions and policy-making processes, and in improving the functioning of democracy. For example, studies that evaluate the effectiveness of voter education programs or analyze voter behavior during electoral reform are highly useful. Furthermore, research on voting behavior provides important data for developing political campaign strategies, enabling candidates to explore ways to more effectively secure voter support.
