Question

When campaign workers are canvassing neighborhoods, one of their goals is to

identify voters who will support their candidate.
sell campaign buttons door to door.
determine the income level of a community.
find out which candidate voters have selected.

Answer 1

identify voters who will support their candidate.

Canvassing is primarily used to locate and persuade supporters, recruit volunteers, get commitments to vote, and improve turnout — not to sell buttons or to learn private post‑vote choices.
