Political parties influence election outcomes by shaping voters' perceptions and preferences. Through campaign strategies, they mobilize support, raise funds, and disseminate political messages. Parties engage in voter outreach and can alter public policy agendas, making certain issues more salient. Their ability to attract coalitions and endorsements can sway undecided voters, significantly impacting election results. Furthermore, party organization affects voter turnout, as well-structured parties often perform better by providing resources and information to their supporters.
