Let's take Civitas as an example. In Civitas, a voter has both "real credentials" and "fake credentials" that they can use to vote. Let's say that the spouse of the voter forces them to vote on a malware-infested machine, at a specific time and and place, while physically watching them vote, and also capturing any forensic evidence available on the machine. In this hypothetical the voter can simply use their fake credentials to cast a fake vote, and later use their real credentials to cast a real vote in secrecy. Will an abusive spouse be convinced that the coercion worked? No, but there is nothing the voter can do to convince the spouse in this case anyway. Even if the voter uses their real credentials to vote, they still have the same problem: they have no ability to convince their spouse that they voted as requested.
