News maps in Arizona, Michigan and Washington were drawn by redistricting commissions. Republicans controlled holding the lines in Kansas and Missouri.
Here’s a look at the key House primaries we’re watching Tuesday:
Republicans are looking at pickup opportunities in several districts made more favorable to the party under the new map.
In the news 2nd District, which Trump would have by 8 points in 2020, several Republicans are challenging Democratic Rep. Tom O’Halleran. They include Navy veteran Eli Crane, who has Trump’s support. State Rep. Walt Blackman, an Army veteran and the first black Republican elected to the Arizona Legislature. and business consultant Mark DeLuzio.
Republicans are also targeting Democratic Rep. Greg Stanton in the Phoenix area 4th District, which Biden would have by 10 points. Top GOP contenders include Tanya Contreras Wheeless, a former Phoenix Suns executive who has the backing of House GOP Conference Chairwoman Elise Stefanik’s PAC, and Marine Corps veteran Kelly Cooper.
Michigan’s new citizen-driven redistricting commission created a congressional map that was deemed more reflective of the purple state.
Republicans, meanwhile, have their eyes on three seats in Michigan.
In the news 10th District, a suburban Detroit seat that would support Trump by 1 point in 2020, Army veteran John James, who lost closer-than-expected US Senate races in 2018 and 2020, is the front-runner for the GOP nomination. James is in the NRCC’s Young Guns program and has Trump’s endorsement. Democrats seeking the seat include former local attorney and judge Carl Marlinga, attorney and Palestinian rights activist Huwaida Arraf and Warren City Council member Angela Rogensues.
The GOP is also targeting Democratic Rep. Elissa Slotkin in the new Lansing-anched 7th District and Dan Kildee in the new 8th District, featuring Flint. Sen. Tom Barrett is the only Republican seeking to challenge Slotkin, while three Republicans are vying to take on Kildy. Biden would almost have both seats.
Meanwhile, two deep blue Detroit-area seats have competitive Democratic primaries. In the news 12th District, Democratic Rep. Rashida Tlaib, a member of the House progressive “caucus,” faces Detroit City Clerk Janice Winfrey, Village of Lathrup Mayor Kelly Garrett and former state Rep. Shanelle Jackson. Out in the open 13th District, top Democrats include state Sen. Adam Hollier, an Army veteran. Michigan Civil Rights Commission Chairwoman Portia Roberson, who has endorsed the retirement of Detroit-area Representative Brenda Lawrence. and self-financed state representative Shri Thanedar, who was a gubernatorial candidate in 2018.
With no swing seats in Missouri, the GOP’s 6-2 advantage in the state’s U.S. House delegation is expected to hold in November. But there are several competitive qualifiers.
In the 4th District, in central Washington, Trump endorsed Army veteran Lauren Culp to face Newhouse, who is seeking a fifth term. Culp was the GOP candidate for governor of Washington in 2020, and even though he lost by more than 500,000 votes, he refused to concede, repeating the same campaign lies as the former President. Newhouse holds a significant fundraising advantage over his opponents, who also include Navy veteran and former NASCAR driver Jerrod Sessler, a Republican, and businessman Doug White, a Democrat.
And two-term Rep. Kim Schrier is again a GOP target in the 8th District, east of Seattle, which Biden would carry by 7 points. Her Republican challengers include Army veteran Jesse Jensen, who lost to Schrier by less than 4 points in 2020. Matt Larkin, who ran unsuccessfully for attorney general in 2020. and King County Councilman Reagan Dunn , whose mother, the late Rep. Jennifer Dunn, represented an earlier version of the district.
