Canvassing, an organized system of face-to-face citizen outreach, has long been used by politicians and advocacy groups to encourage constituents to vote, assess the habits and preferences of voters, and gather public opinion data. The time-honored tradition of knocking on doors remains an integral part of campaigns, though new mobile technology is starting to change the way canvassers operate on the ground.

Though the studio lights have dimmed for the last time on Jon Stewart’s tenure as host of The Daily Show, his brand of political satire -- which aimed to keep leaders accountable, the media honest and youth interested in government -- shines on through its immense success with young audiences at home and abroad. The Daily Show sparked a new era of political satire, a step beyond the traditional editorial cartoon, satirical magazine and occasional political joke on late-night television. In the United States, Stewart’s style of “fake news” revolutionized not only satire in (and of) the media, but how youth engage with politics.
