1.NOTIFY YOUR LOCAL POLICE/SHERRIF IN ADVANCE
If they know beforehand, they will be better ready to accompany or protect voters, especially in long lines. Don't be afraid to report anything fishy you see, especially in long lines.
2.KNOW YOUR POLLING STATION LAWS
If your polling stations allows self-defense items or measures such as concealed carry, or what have you, then utilize it to the best of your ability, should the worst happen.
3.GO IN GROUPS, DO -NOT- BE INTIMIDATED
Even if it's young to elderly, go in support groups if need be to the polls and look after one another, especially those prone to being scared off due to violence.
4.PLAN YOUR ROUTES/FIND ALTERNATE ROUTES
This is ESPECIALLY essential if you live in big cities or areas. If there are any other polling stations around, find alternate routes to them instead of routes where ANTIFA/BLM may frequent or march. There should be more than one on the third, so try to find safe routes around them to get to another if need be.
This also should prevent traffic shutdown, should they try it. If you are screamed at to stop, absolutely do NOT STOP. Turn around, go to another.
5.DO -NOT- WEAR ADVERTISING GEAR ON YOUR PERSON
They will be looking for those in patriotic gear/trump gear/masks/flags/what have you, and in most polling areas, you can't wear anything that advertises your political leanings, so for the love of god leave your gear at home, until you get home!
6.ARRIVE EARLY MORNING IF YOU CAN
They can NOT be up that early, so make plans, or call days off to vote very early in the morning ON THE THIRD to circumvent any potential conflicts.
7.FIND OUT IF THE NATIONAL GUARD IS PROTECTING YOUR POLLING STATIONS
They are supposed to be deployed in 12 states, so figure out if they're protecting your state/county's polling stations, and if not, arrange to have them do so.
Consider conceal carry.
Do they allow that during polling places?
If you don’t get caught then anything is allowed.
