If all of the Clerk, Inspector, Judges positions are filled at your county election board; ask the local GOP president if they have a job for you. Many people running for office need help at the larger polls to pass out material. There are many ways to get involved.
My grandparents, parents and now I have worked our local election boards It is a great way to contribute to your community.
Been doing that for over 25 years now, including a stint as an officer on the county grand jury. Into 5 figures in political donations... ;)
