When do polls close in Missouri?

Polls are open 6 a.m. to 7 p.m., and voters in line at 7 p.m. have the right to cast a ballot. Absentee ballots must be received by the local election authority by the 7 p.m. poll closing on Election Day to be counted (a receipt deadline); valid military and overseas ballots count if received before noon on Friday, Nov. 6.
