Primary Recap: Marshall Wins GOP Senate Nomination in Kansas; Two House Members Ousted

Five states held their primaries on Tuesday. Click or tap to view full live results by state:

Kansas Republicans solidify general election prospects:  Rep. Roger Marshall defeated former Secretary of State Kris Kobach to win the GOP Senate nomination, while in District 2, state Treasurer Jake LaTurner ousted incumbent Rep. Steve Watkins. In both cases, voters chose the candidate favored by party leaders and who likely had the best general election prospects. 

Kansas hasn't elected a Democratic Senator since 1932. While the race isn't completely off the competitive radar - Democratic nominee State Sen. Barbara Bollier is a credible nominee - the controversial Kobach would have been a tougher sell to the full electorate. The same could be said of Watkins, who was recently charged with multiple felonies. Cook Political moved this Topeka-area district from Leans to Likely Republican.

Dynastic Congressman ousted in Missouri:  The Clay family has held Missouri's first congressional district since 1969. That will end this year, as Rep. Lacy Clay was defeated by progressive challenger Cori Bush. This is a safely Democratic seat, so Bush will almost certainly be the next representative of this St. Louis district.

With Tuesday's results, seven U.S. House incumbents have been defeated in party primaries this year. That is the most in a non-redistricting cycle since 1974.  Our Retirement Map shows these, as well as candidates who voluntarily chose not to run for reelection this year.

Arizona:  As expected, Sen. Martha McSally easily won the GOP nomination. She starts as the underdog in a general election battle against Democrat Mark Kelly.

Kansas:  Former Lt. Gov. Tracey Mann won the District 1 GOP nomination. This is the seat being vacated by Marshall, now the Senate nominee. This is a safe Republican seat, making Mann the heavy favorite in November.

Michigan:  In District 3, grocery scion Peter Meijer won the GOP nomination for the seat being vacated by former Republican Justin Amash. In District 6, political newcomer Jen Richardson is leading State Rep. Jon Hoadley in the Democratic primary to take on Rep. Fred Upton. This would be an upset. Lisa McClain won the GOP nomination in the open District 10. This is safe Republican territory. In District 13, 'Squad' member Rep. Rashida Tlaib has a substantial lead over Brenda Jones. The race hasn't been called as of this writing due to a large number of uncounted absentee ballots.

Missouri: As expected, GOP Gov. Mike Parson and Democratic State Auditor Nicole Galloway easily won their respective nominations. Parson starts as the favorite in the general election.

Washington: Gov. Jay Inslee was renominated for a third term. He is a prohibitive favorite in November against Republican Loren Culp, who finished second in the top two primary. The primary in District 10 remains uncalled as of this morning. A large field is vying to replace Democratic Rep. Denny Heck.  It looks like both of the top two finishers will be Democrats. Heck is running for Lt. Governor, and appears to have secured a spot in the general election.
