Voting sites really don’t cost that much money. They probably spent more money putting up this measure than it would cost to just run the damn thing.
When I work elections, the county pays me roughly 180 bucks for the whole day 6am - 8pm (I dont do it for the money, obviously). The smallest one i worked had around 3-5 people, so less than 1k in labor overall.
All of the devices and materials aside from the ballots get re-used for each election, unless there are equipment changes. The voting locations themselves are often donated spaces, like churches and schools. There are also election technicians, but they’re serving multiple precincts and dropping one location won’t make much of a difference. Everyone else involved is usually already a salaried government worker.
All this to say, closing a precinct to “save money” is a pathetic excuse. Everyone has the right to vote. It should be the first thing we make sure we budget for.
