Maintaining a two-party system poses several challenges, including the potential for political polarization, where extreme viewpoints dominate, often sidelining moderate voices. This polarization can lead to gridlock, making it difficult for the government to enact meaningful legislation. Additionally, a two-party system can result in voter disenfranchisement, as individuals may feel compelled to choose between two dominant parties, despite having differing views. It can also stifle political competition, as third parties struggle to gain traction in elections. Addressing these challenges often requires reforms to encourage more diverse representation.
