Voter turnout in U.S. elections tends to fluctuate, with multiple factors influencing a prospective voter’s participation. In this investigation, we focus on how a registered voter might change their inclination to participate in an election based on their perception of others’ political views within their community. We present an agent-based model (ABM) designed to explore community-based driving mechanisms of voter turnout and election outcomes. By conducting a sensitivity analysis, we examine which of our model inputs—including factors such as party-affiliation breakdown or the degree to which voters tend to communicate in echo chambers—have the greatest impact on voter turnout and the extent to which election results accurately represent the majority opinion in the electorate. We find that within our model framework, turnout rates depend heavily on party affiliation heterogeneity as well as how strongly a voter is influenced to vote or abstain by their politically-based interactions within their community. Additionally, we find that it is possible for an unexpected winner to emerge victorious due to an increase in mobilization among minority party members under certain conditions.
