When voting today, do not wear things that endorse candidates, do not bring a firearm to a polling place and do not be inside a polling place other than to vote or with pre-approved authorization.
Those were among the messages the Missouri secretary of state reminded voters of ahead of today's general election.
Secretary of State Jay Ashcroft said in a news release issued Monday: "With Missourians across the state set to cast their ballots tomorrow, we want to ensure voters know what they will encounter at their polling places."
Polls open at 6 a.m. and close at 7 p.m. - though anyone in line at 7 p.m. is entitled to cast their ballot.
Ashcroft's office cited state law that prohibits wearing anything to the polls that advocates for a political candidate or issue - including masks, shirts, hats and buttons.
That law - 115.637 RSMo - does not directly reference "apparel" or "clothing," but a spokesman for Ashcroft's office said that's covered by an included provision that prohibits electioneering and other activities inside a polling place or within 25 feet of the door.
State law - 115.409 RSMo - also limits who can be inside a polling place to only registered voters who are eligible to vote, poll workers and other election authorities; children under age 18 accompanying an adult voter; law enforcement officers requested by election officials or in the line of duty; and other pre-approved poll watchers, observers and other people with special designation.
According to the Associated Press, while President Donald Trump has been urging his supporters to go the polls and "watch very carefully" - raising concerns about possible voter intimidation - election monitoring is "not a free-for-all."
News media may be inside a polling place, but per Missouri law must present identification satisfactory to election judges, and coverage cannot violate the law's electioneering prohibition or certain other conditions inside, such as not disclosing how a voter voted.
Voters themselves are prohibited from showing their ballot to others to show how they are about to vote or have voted, which is why Ashcroft's office advised that "voters may not take photos inside their polling place."
"On Election Day, we urge voters to focus their political passion on their ballot instead of their apparel, and refrain from taking selfies or other photos in their polling place," Ashcroft said.
Firearms and other lethal weapons are also not allowed inside a polling place on Election Day.
The Secretary of State's Office advised voters who encounter any issues or have questions today are encouraged to contact their local election authority or call the secretary of state's office at 800-669-8683.
The Secretary of State's Office election night reporting website - sos.mo.gov/elections/s_default - will not be activated until each polling place has closed and all voters have cast their ballot.
Unofficial results will continue to be updated throughout the night, and local election authorities may begin posting results prior to those that appear on the state's reporting site.
