How has the constitution helped promote political parties in the United States?

The Electoral College comprising of elected and appointed members from different States voted for aspirants with the leading aspirant and the first runners-up becoming the president and vice president respectively. However, ratification of the 12th Amendment changed the operations of the Electoral College by requiring separate elections for both the president and the vice president. This provided parties with an opportunity to select the candidates to run for the two positions effectively recognizing the role of political parties in the American electoral process and governance.

The right to vote through constitutional amendments expanded in most states by extending the right to include all adult white males. This was later expanded to include all citizens above 18 regardless of their previous state of servitude, race, gender and color. Further, changes to the voting rights such as poll tax led to changes in the electoral system which brought wider public participation in the electoral process. The size of the electorate forced the political parties to become more aggressive in their campaigns and aspirant selection. The parties had to increase their influence among the public to garner support for their candidates as is the case currently.
