Kansas, April 11. Jim Thompson (D). 4th Congressional District of Kansas will hold a special election for the U.S. House of Representatives on April 11, 2017. Heading into the election, this race is considered safe for Republican by some – but maybe not. Ron Estes (R), Jim Thompson (D), and Chris Rockhold (L) will compete in the general election on April 11, 2017. No primary elections were held in the race; the candidates were chosen at their respective party nominating conventions in February. The election will replace Mike Pompeo (R), who was selected as director of the CIA. The election will be the first congressional election to take place since Donald Trump’s election to the presidency in November 2016. Despite the district being a traditional long-standing Republican stronghold, Donald Trump defeated Hillary Clinton by a margin of 1.5 percent in the 2016 presidential election. Trump’s average margin of victory in congressional districts that he won was 23.2 percent. Comparatively, Barack Obama lost the district by margins of 23.3 percent and 18 percent in 2012 and 2008, respectively. Trump’s relative unpopularity in the district in 2016 signaled to the Democratic Party that they could potentially pick up the seat in the special election. In February 2017, the DCCC paid to put nine staffers on the ground in the district in an attempt to reach voters who had not been targeted in prior election cycles. The Congressional Leadership Fund, a Republican super PAC, also began spending in the race by launching a $1.1 million ad campaign targeting the Democratic front-runner in the race, Jon Ossoff. According to the few polls released thus far, Ossoff leads the field. He is trailed by the three Republican front-runners in the race, former Georgia Secretary of State Karen Handel, businessman Bob Gray, and state Sen. Judson Hill.

Georgia, April 18. Jon Ossoff (D) is the most viable D in the race. The 6th Congressional District of Georgia will hold a special election for the U.S. House of Representatives on April 18, 2017. Heading into the election, this race is considered safe for Republicans. The election will replace Tom Price (R), who was confirmed as U.S. secretary of health and human services. Prior to his cabinet appointment, Price represented the 6th District from 2004 to 2017. Eighteen candidates filed to run in the race: 11 Republicans, five Democrats, and two independents. A traditional primary election will not be held in the race. Instead, all candidates will compete in the same general election on April 18, 2017. If no candidate receives at least 50 percent of the vote, the top two, regardless of party affiliation, will advance to the runoff election on June 20. With so many candidates in the race, a runoff election is almost assured.

Montana, May 25. Rob Quist (D) Heading into the election, This race was considered safe for Republicans but the Mr Quist is now ahead. The election will replace Ryan Zinke (R) who was confirmed as secretary of the U.S. Department of the Interior on March 1, 2017. Primary elections were not held in the race. Instead, party leaders chose the nominees at conventions. Democrats selected musician Rob Quist at the party’s convention on March 5, 2017, while Republicans nominated businessman Greg Gianforte at the convention on March 6, 2017. The two candidates will face off with the Libertarian nominee, Mark Wicks, in the general election on May 25, 2017.

South Carolina, June 5. Three Democrats in the race. The 5th Congressional District of South Carolina will hold a special election for the U.S. House of Representatives on June 20, 2017. Heading into the election, This race is considered safe for Republican by some but not others. The election will replace Mick Mulvaney (R) who was confirmed as director of the U.S. Office of Management and Budget. Filing closed in the race on March 13, 2017. Fifteen candidates filed in the race: three Democrats, seven Republicans, and five third-party candidates. Primary elections will be held on May 2, 2017, with primary runoffs occurring on May 16 if required.

California, June 6. Two Democrats in the race. The 34th Congressional District of California will hold a special election for the U.S. House of Representatives on June 6, 2017, with a primary election taking place on April 4, 2017. Considered safe for Democratic. The election will replace Xavier Becerra (D), who was appointed as California’s attorney general. Twenty-three candidates filed to run in the race: 19 Democrats, one Republican, and three others. All candidates will compete in the same primary, and the top two—regardless of party affiliation—will advance to the general election. Should one candidate receive more than 50 percent of the primary vote, a general election will not occur. The past two elections in the district have featured a general election contest between two Democrats, a likely scenario in this special election as well.
