The purpose of public opinion polls in politics is to gauge the sentiments and preferences of the electorate. These polls provide insights into voter attitudes regarding candidates, policies, and current events, helping political strategists shape their approaches. By understanding public opinion, candidates can tailor their messages and campaign platforms to align with voter concerns. Polls also foster accountability, as they inform leaders about the public's approval or disapproval of their actions. Overall, public opinion polls play a vital role in reflecting and influencing the democratic process.
