Missouri: How to vote, where to vote and what’s on the ballot.

Missouri voters will weigh in on Tuesday on some key primary contests, including who gets the Republican nomination in the race to replace the retiring Senator Roy Blunt.

Not sure if you can vote? Want to vote but don’t know where to go? What else is on the ballot?

Here is a handy, last-minute guide to Election Day in Missouri.

How to vote

July 6 was the deadline to register to vote in the Aug. 2 primary. (But you have until Oct. 12 to register to vote in the general election, which is Nov. 8.)

Not sure if you’re registered? Check on this page of the Missouri secretary of state website, where you can also see a sample of the ballot in your area.

Where to vote

Voting sites are open on Election Day from 6 a.m. to 7 p.m. Central time. The same page we linked to above will also help you find your voting site.

If you are voting with an absentee ballot, you must get it to your local election authority by the time the polls close, according to the secretary of state’s office. The deadline to request an absentee ballot was two weeks ago.

What’s on the ballot

There are primary contests in each of the state’s eight House districts. Statewide, Democrats and Republicans have crowded Senate primaries to replace Mr. Blunt. There are 11 Democrats on the ballot, including two with the last name Kelly (Jewel Kelly Jr. and Pat Kelly).

There are 21 candidates in the Republican Senate primary. They include former Gov. Eric Greitens, who resigned in 2018 after accusations of sexual abuse from his former hairdresser. Also on the Republican ballot is Mark McCloskey, a lawyer who pleaded guilty last year to misdemeanor charges after he and his wife pointed guns at protesters marching outside their home.
