Some local election officials said the state’s website has the most up-to-date information on the new polling sites. Local election authorities provide sample ballots, which voters can study, fill out and bring with them on Election Day to use as a guide. To cast a regular ballot, registered Missouri voters must present photo identification issued by Missouri or the federal government. If you cast a provisional ballot, you will receive a stub from your provisional ballot envelope with instructions on how to verify that your provisional ballot is counted. Electioneering is also prohibited within at least 25 feet of the building’s closest outside door, although some local election authorities may establish a 50-foot boundary.
