Social media has transformed modern political campaigns by enabling direct communication between candidates and voters. Platforms like Twitter and Facebook facilitate rapid information sharing, allowing campaigns to react swiftly to events and engage with constituents in real time. However, the prevalence of misinformation and echo chambers can distort public perception and drive polarization. Social media's influence allows for both grassroots mobilization and targeted advertising, shaping voter behavior significantly during elections. Its immediacy and accessibility have made it an essential tool for modern campaigning, but also pose challenges in maintaining truthfulness and democratic dialogue.
