JEFFERSON CITY, Mo. (AP) - It's the last call for people pondering a run for public office in Missouri.
The end of business Tuesday marks the deadline to file for a federal, state or local office in this year's party primary elections.
Missouri's primaries will be held Aug. 3, with the winners facing off in the November general election.
A record 417 people filed for office on the first day possible in February. But since then, the pace has slowed. Heading into Tuesday, 537 candidates had filed for office.
Among them are 18 candidates for U.S. Senate, where the front-runners are Democrat Robin Carnahan and Republican Roy Blunt.
