  Political scientists have distinguished between different types of political parties that have evolved throughout history. These include elite parties, mass parties, catch-all parties and cartel parties. Elite parties were political elites that were concerned with contesting elections and restricted the influence of outsiders, who were only required to assist in election campaigns. Mass parties tried to recruit new members who were a source of party income and were often expected to spread party ideology as well as assist in elections. In the United States, where both major parties were elite parties, the introduction of primaries and other reforms has transformed them so that power is held by activists who compete over influence and nomination of candidates.
