Put the fliers on legal posting places (telephone poles, your own trash cans and fences, possibly at gun stores, in the windows of friendly businesses and send to every politician in your area).
Make the war on the Left visible and continuous. Make them look over their shoulders for once at the angry voters coming after them.
If they don’t respect you, make them fear you.
I was thinking gun shops and shooting ranges because of the customers who go there. Hopefully between them and the like minded people they hang out with might motivate more to the cause.
Any leftists who see the flyers would just take them and throw them in the trash. Less likely to happen in a gun shop or shooting range.
