Question

Quizplus · Accepted Answer

Third parties are usually not successful in winning elections, but they can play a significant role in influencing the major parties' policies. By introducing new ideas or highlighting issues that major parties may have neglected, third parties push major parties to incorporate these ideas or address these issues. This makes third parties significant in shaping the overall political discourse and policy agenda of the country.
