In 3 weeks, if someone goes to vote at a polling location and doesn't wear a mask, can they be stopped from voting?
There is no Federal mandate for masks.
This is a Federal Election. The work is executed locally and state-wide but there are Federal rules. Preventing a voter from voting is at the top of the Federal No-No list.
There are rules saying you can't wear or must cover electioneering materials. Beyond minimal decency, there's no dress code to vote.
(This is a thought experiment. Wear a plain mask if you must and get Trump reelected instead of making a point and turning the Oval over to 2 arrogant liars. If you live in a solidly blue state, Trump still needs your vote to win the popular count.)
I contacted my local election bureau. Confirmed 1. All polling stations opened, no change, same place as always. 2. Will you be turned away if you dont wear a mask? They said they will never turn anyone away. While highly encouraged, you will not be denied you constitutional right to vote due to a mask 'mandate'. SO I WILL VOTE IN PERSON ON ELECTION DAY AS NORMAL WITH MY FACE.
