The field department focuses on the "on-the-ground" organizing that is required in order to personally contact voters through canvassing, phone calls, and building local events. Voter contact helps construct and clean the campaign's voter file in order to help better target voter persuasion and identify which voters a campaign most wants to bring out on election day. Field is generally also tasked with running local "storefront" campaign offices as well as organizing phone banks and staging locations for canvasses and other campaign events.
