Do members of the same household share similar voting behaviors because of their influence on each other?
There have been studies showing that members of the same household share similar voting behaviors on average. Researchers performed a face-to-face canvassing experiment in various cities. They visited households with two registered voters. Residents who answered the door received either a Get Out the Vote message or a recycled pitch. Then they looked at whether or not the person in each household who did not answer the door went to vote.
