Party primaries significantly influence election outcomes by determining which candidates represent each political party in general elections. This process often pits candidates against each other in competitive elections, where voters can express their preferences. The outcomes can shift party platforms and strategies based on the winning candidate's appeal to the electorate. Additionally, strong primary performances can boost candidate visibility and fundraising efforts, impacting their chances in the general election. Thus, party primaries serve as a critical filter in shaping the political landscape.
