As reported by UncoverDC, Harris trained hundreds of volunteers to go door-to-door to canvass "vacant lots, hotels, county buildings, apartment complexes with no corresponding apartment number, abandoned properties, non-existent addresses, homes for elderly, churches, sports arenas, homeless shelters, native American reservations." The independently-run grassroots canvass is a crucial piece in the puzzle for election integrity because it seeks to reconcile the voter database with the voter rolls. A simple count of votes does not necessarily reflect the will of the voters.
