Public opinion polls influence political campaigns by providing candidates with insights into voter attitudes, preferences, and concerns. Campaigns utilize this data to tailor their messaging, prioritize issues, and determine where to allocate resources effectively. Polls can create a sense of momentum or urgency, affecting fundraising and volunteer mobilization. Additionally, they can shift campaign strategies in real-time, prompting candidates to adjust their stances to align with voter expectations. However, reliance on polls can lead to bandwagon effects, where candidates focus on popular topics rather than broader policy issues.
