Note that Boone County offices, including the County Clerk, are closed on Monday October 8, 2018.
If you opt to register to vote in another district (another part of Missouri or another state), unless you travel there to vote, you will need to apply for an absentee ballot. If you choose to do this, you must make sure you know the other jurisdiction's procedures and deadlines, and allow ample extra time to allow for unforeseen glitches, if you want your vote to count. See the "Every State Votes Differently" section of this guide for a few examples of state-by-state differences. Check the procedures and deadlines now to ensure your vote will count.
Do not forget, if this is your first time voting in the state of Missouri, you will need to vote in person, if you did not present photo ID to your County Clerk at the time you registered.
