Two-party system
Third parties, meaning a party other than one of the two dominant parties, are possible in two-party systems, but they are often unlikely to exert much influence by gaining control of legislatures or by winning elections. While there are occasional opinions in the media expressed about the possibility of third parties emerging in the United States, for example, political insiders such as the 1980 presidential candidate John Anderson think the chances of one appearing in the early twenty-first century is remote. A report in "The Guardian" suggested that American politics has been "stuck in a two-way fight between Republicans and Democrats" since the Civil War, and that third-party runs had little meaningful success.
Federalist No. 67
In modern society, the government, especially the executive branch, has struggled with the ever-growing mixture of republican and energetic governments. The executive branch can be held by two major political parties: the Democrats and the Republicans. The elections that take place every four years, unequal representation within Congress, and differing opinions makes it difficult to find a balance within the Executives. Each new term brings in new faces, who come with new ideas and backgrounds. This rapid exchange of power often leads to a president who tries to do too much in too little of time, which forces a president to be the main problem solver despite having Congress for guidance or intellectual support. This contributes to the overall sense that the president may hold too much power - much like a forceful dictator.
