Rep. David Reichert, R-Wash., announced Wednesday he will not seek an eighth term in office.
"After spending time during the August recess work period with family and friends, reflecting on the past, discussing the future, and celebrating another birthday, I have decided this will be my last term, and I will not run for reelection in November 2018," Reichert said in a statement.
Reichert, 67, said his decision to no longer represent the Evergreen State's 8th congressional district was "not an easy decision," but the right one for his family.
"It has been an honor and a privilege to serve the people of the greatest state in the world's greatest nation for nearly five decades," Reichert added.
The congressman faced tense townhall crowds at events during August. Reichert was facing a challenging reelection because a handful of Democrats have already jumped into the primary race.
The Democratic Congressional Campaign Committee (DCCC) had targeted Reichert's seat back in January and speculated the could be up for retirement back in May.
DCCC spokesman Drew Godnich said Reichert's decision makes the district a toss-up.
"It's become increasingly clear that the Republican Party is out of step with the values of western Washington, and Dave Reichert's retirement is testament to how wide that gap has grown," he said. "As one of the most Democratic districts held by a Republican Representative, this district was always going to be competitive.
"Clearly, Congressman Reichert saw the writing on the wall, and realized that he was in for an uphill re-election campaign against a strong bench of Democratic challengers with a motivated base, while defending congressional Republicans' failed legislative agenda, particularly on healthcare repeal. Democrats are confident that the people of the 8th District will finally have a Democrat representing their values in DC after next November."
According to a national GOP operative, State Sen. Dino Rossi, a two-time GOP gubernatorial nominee and a one-time Senate nominee in the state, is being floated as a potential candidate to run and replace the outgoing congressman. Most recently, Rossi lost to Sen. Patty Murray, D-Wash., by five points in 2010.
"Washington's Eighth District is a seat that has chosen Republicans for over a decade," said Rep. Steve Stivers, R-Ohio, chairman of the National Republican Congressional Committee, in a statement.
"With a bitter and expensive primary fight already confronting Democrats in this seat, Republicans are ready to elect another common-sense congressman like Dave Reichert, not another rubber stamp for Nancy Pelosi."
