[From obsolete canvass, to toss in a canvas sheet as punishment, from CANVAS.]
canvasser can'vass·er n.Canvass, to ascertain by direct personal approach how citizens intend to vote in a coming election or to seek public opinion on a candidate or issue. The practice was somewhat less common in the early 2000s because of polls made by local Newspapers and by magazines of wide national circulation, as well as polls taken by more sophisticated methods used by professional polling services. More loosely, to canvass means to campaign for the support of a given candidate or for the political ticket supported by a given party. Canvass also refers to an official examination of ballots cast in an election to determine authenticity and to verify the outcome of the election.
