While the American system of politics has generally been defined as a two-party system, occasionally a third party emerges, influencing elections and siphoning important votes from the major parties. Third parties often begin as single-issue parties that oppose or promote a certain social, economic, or political topic. For example, the Republican Party formed in the 1850’s as a third party in opposition to slavery. Similarly, in 2000, Ralph Nader formed the Green Party that focused on environm
Demography is the study of the characteristics of the human population, such as age, race, and gender. Political scientists use demography to identify and study specific target groups to determine who shows up at the polls versus who does not.
