On Wednesday, Gov. Steve Bullock called a special election to take place on May 25 to fill Montana’s only seat in the U.S. House of Representatives vacated by Ryan Zinke.

Zinke was confirmed this week by the U.S. Senate as President Donald Trump’s new Interior Department secretary.

Zinke has refrained from participating in dozens of House votes since his cabinet nomination, leaving Montana without representation for most of 2017.

So far, seven Republicans and eight Democrats have filed for candidacy seeking the respective party nominations. The Democratic Party will hold a special nominating convention on March 5.

Ohio state Rep. Greta Johnson announced her resignation this morning, effective at the end of the month.

She is stepping down to take a position as deputy law director for Summit County Executive Ilene Shapiro.

Johnson was elected in 2014 to represent District 35. Prior to serving in the Legislature, she served as a prosecutor in Mahoning County and Summit County, as well as with the city of Akron.

The House Democratic Caucus will soon announce the process for selecting her replacement.

On April 3, five by-elections will be held for the Canadian House of Commons. On February 22, Prime Minister Justin Trudeau announced four by-elections for the electoral districts of Saint-Laurent, Quebec, Calgary Heritage and Calgary Midnapore, Alberta, and Markham—Thornhill, Ontario. Trudeau had previously announced on February 19 a by-election would be held for the electoral district of Ottawa—Vanier, Ontario.

The vacancies requiring the by-elections came about for different reasons. Last year, former prime minister Stephen Harper and member of Parliament(MP) Jason Kenney resigned from their House of Commons seat representing electoral districts Calgary Heritage and Calgary Midnapore, respectively.

The seats for electoral districts Saint-Laurent and Markham-Thornhill were left vacant last month after ministers Stephane Dion and John McCallum were named to diplomatic posts, according to the Globe and Mail. The seat representing electoral district Ottawa-Vanier became vacant when MP Mauril Belanger died last year from amyotrophic lateral sclerosis.

Oklahoma Gov. Mary Fallin scheduled a special election to fill the upcoming vacancy in House District 75. Rep. Dan Kirby will voluntarily vacate the seat on March 1.

Kirby’s resignation allows him to avoid a potentially embarrassing floor vote to remove him from the legislative body amid sexual harassment allegations.

House Speaker Charles McCall had previously suspended Kirby from his chairmanship of the Business, Commerce, and Tourism Committee pending further investigation of the allegations. Kirby denies any wrongdoing.

A special primary election will be held May 9 with a special general election on July 11. If a special primary is not necessary, the May 9 election will be considered the special general election.

State Rep. Brian Banks resigned as part of a plea deal related to charges involving fraudulent pay stubs.

To fill the vacancy, Gov. Rick Snyder announced a special election to fill the First House District seat.

The special primary will be held on August 8, 2017, and the special general election will be held on November 7, 2017.

The special election coincides with the regular election to save taxpayers money.

Special elections will be held on June 20, 2017, to fill vacancies in South Carolina state House Districts 48 and 70, as well as in the state’s 5th congressional district.

District 70 was left vacant last week following the death of state Rep. Joseph Neal.

State Rep. Ralph Norman, representing District 48, resigned his seat last week to run for South Carolina’s 5th congressional district.

Former U.S. Rep Mick Mulvaney vacated his District 5 seat when he was confirmed as the director of the Office of Management and Budget.

State Rep. Ralph Norman resigned his seat last week to focus on his campaign for U.S. House. The move puts pressure on his colleague and current state House Speaker Pro Tempore Tommy Pope to do the same.

The men are among a half-dozen GOP candidates running to replace former U.S. Rep. Mick Mulvaney. Mulvaney represented South Carolina’s congressional district until confirmed as the director of the Office of Management and Budget.

Norman’s move will save the taxpayers thousands of dollars if the election to fill his seat is held on the same day as the district race.

Pope is not planning to resign his House seat in light of the congressional race.

Gov. Nathan Deal announced a special election will be held on April 18, 2017, for state Senate District 32.

Sen. Judson Hill resigned from the seat to run in the special election for the Sixth Congressional District, scheduled for the same day, to replace Rep. Tom Price.

U.S. Sen. Jeff Sessions was confirmed as President Trump’s attorney general on February 8, 2017.

To fill the Senate vacancy, Gov. Robert Bentley has appointed state Attorney General Luther Strange to succeed Sessions. Bentley’s appointee will serve the U.S. Senate with 22 months of incumbency until the next general election.

Some controversy surrounds Bentley’s appointment; state Auditor Jim Ziegler filed a written request with Bentley opposing his decision to appoint a replacement and hold off with special elections until November 2018.

Ziegler cited Alabama code stating a special election could only be delayed until the next regular election if the senate vacancy occurred within four months of the next regular election.

A special election has been set for May 6, 2017, to fill the vacant seat for the Mayor of Corpus Christi, Texas.

Dan McQueen, former mayor, resigned on January 18 after just 37 days in office. His resignation came after being the subject of intense media scrutiny for criticizing city council and local media members on social media.

During such time, it was revealed that McQueen, who had no previous experience with public office, hired his live-in girlfriend as his chief of staff without disclosure to the city manager in direct conflict with the city’s policies.

Since McQueen’s resignation seven candidates have entered the mayoral race, including the City’s current Ethics Commissioner, Larry White.
