Those lines are on purpose. The red states don't put enough voting machines in the polling places or they put malfunctioning machines. They close voting places so there's only one or two for hundreds of thousands of people to vote.
We don't have those problems here. Even when we did vote at voting booths.
We went 100% mail in ballot in 2005 so no one ever stands in line or is ever denied their right to vote.
Registering to vote is easy and voting is easy here. It should be that way in every state.
The republicans know that they lose if everyone votes so they do everything they can to prevent democrats from voting.
It should be illegal but it's not.
If I lived in a red state I would never vote in person at voting place. I would always vote mail in ballot.
My question is...who's in charge of closing and/or opening these voting precincts?
I'm not sure but I think that the Secretary of State of each specific state will be the person who at least signs off on where and how many precincts there will be.
I did a search on your question and it looks like it might be different depending on the state.
This is an article from June about Georgia. It lists, at least for that state, who is in charge of what in Georgia.
My state doesn't have polling places we're 100% mail in. So there is no precinct voting place that can be closed or opened.
Here's how Georgia elections technically work.
