Persuasion of voters in a political campaign

Door-to-door is a canvassing technique that is generally used for sales, marketing, advertising, evangelism or campaigning, in which the person or persons walk from the door of one house to the door of another, trying to sell or advertise a product or service to the general public or gather information.

"Canvassing" is the second episode of the first season of the American comedy television series Parks and Recreation.
