Gov. Jay Nixon plans to set June 4 as the special election date to fill the vacant seat in the Eighth District in southeast Missouri.
Rep. Jo Ann Emerson sent Nixon a letter Tuesday notifying him that her resignation from the seat would be effective at 11:59 p.m.
Under Missouri law, the notice of election must be submitted to local election authorities no later than 10 weeks prior to the election. And under the Military and Overseas Voter Empowerment Act, the deadline for military ballots to be printed and made available, and for local election authorities to begin transmitting those ballots to military and overseas voters, is 45 days before a special election for federal office.
The deadline for candidates to file is no later than 5 p.m. on the day that is the midpoint between the date when the election is called and special election day.
Nixon plans to officially set the June 4 special election date on Wednesday.
