Canvassing is a form of campaigning in which people go door-to-door to solicit votes for a particular candidate or cause. It is a common practice in many countries, and it is often used to increase voter turnout. Canvassing involves talking to people in their homes or on the street, and it can be an effective way to spread awareness about a particular issue or candidate. By canvassing, candidates can reach out to potential voters and encourage them to cast their ballots.
