Lutherans teach a concept called "vocation" in which God utilizes us in this world to do His work. Luther wrote extensively on it, and I suggest reading his words and explanation as they are much clearer than can ever be posted on a blog. Some examples posted by the LC-MS are here, and there are books that can be ordered with further developments that I won't list here due to length. In the United States, Nov. 3 is an election day. Not all states have elections as each state has its own cycle. Virginia votes on local elections this year, and I believe at least a few others do as well. In any case, if there is an election for you, it is part of your vocation as a citizen to vote. Many people don't "get into" anything that isn't a major election, like governor or President. The truth is your vocation obligates you to weigh the candidates and vote accordingly regardless of the level of the election.
Please fulfill your vocation and vote if you have the opportunity. If you don't, you can still fulfill your obligation as a citizen to encourage those who can vote to do so, and to be current on the issues important to your local, state, and national level government. Each level has different concerns and responsibilities, and those need to be weighed with thoughtful Christian consideration for what is the wisest course of action.
