Question

Quizplus · Accepted Answer

The rules and regulations on campaigns make it difficult for third-party candidates to gain visibility and credibility, as well as access to public funding and media coverage. This gives a significant advantage to the two major parties, making it hard for third-party candidates to mount a viable campaign. Factors such as Americans' party identification and low voter turnout rates also play a role, but the rules and regulations on campaigns are the most significant factor. The fact that Election Day is on a workday also poses some challenges, but it is not a major factor contributing to the two-party system.
