I'm confused. Are you talking about family members forcing others to vote a certain way? Wouldnt that family member be just as coercive at a polling station? I guess in theory one could lie to the family member if they vote in person but is this a sizable and real concern about at home voting? Genuinely curious because I've never heard of anyone expressing this concern before.
