In the battle of progressive Democrats for the competitive open seat race for 7th Congressional District, State Senator Pramila Jayapal emerged the winner after State Representative Brady Walkinshaw conceded.

Voter totals Tuesday night showed Jayapal leading by 57% to Walkinson's 43%.

Both candidates are progressive Democrats in one of the most progressive districts in the state. And it's a seat left open by longtime Seattle Democratic Congressman Jim McDermott, who's retiring after 28 years in office.

This election also marks the first time two Democrats ran against each other in the 7th District since Washington's top two primary system took effect eight years ago.

The 7th Congressional District encompasses most of Seattle, Vashon Island, Edmonds, Shoreline and Burien. The Wall Street Journal called the district “one of the country’s most liberal” and noted candidates struggled to answer a KCTS/Crosscut debate question about “the most conservative position you hold.”

Jayapal, who lives in the Columbia City neighborhood just outside of the 7th Congressional District boundaries, received a pre-primary boost from Vermont Sen. Bernie Sanders, whom she supported in the presidential caucuses. Before her election to state Senate, Jayapal was a Seattle-based civil rights activist, serving as the executive director of OneAmerica, a pro-immigration advocacy group until 2012.

Walkinshaw has worked on international food policy at the Gates Foundation before his appointment to the state House in 2013.
