House Republican Conference Chairwoman Cathy McMorris Rodgers narrowly secured the top spot in her primary in Washington on Tuesday, which could embolden Democrats looking to unseat the only woman in GOP leadership.

Under Washington’s top-two primary system, all candidates run on the same ballot and the two with the most votes, regardless of party, advance to November. 

With 46 percent of 5th District precincts reporting, McMorris led with 48 percent of the vote to 47 percent for Democrat Lisa Brown, when The Associated Press called the race.

Brown, a former Washington State University Spokane chancellor, was the only Democrat on the ballot, which also featured two other Republicans and one third party candidate. Inside Elections with Nathan L. Gonzales rates the race for Eastern Washington seat Likely Republican.

An aide to McMorris Rodgers noted in an email that votes were still being counted, and that the congresswoman received 42 percent of the primary vote in 2016. She went on to win the general election by 19 points.

Democrats have touted Brown, a onetime majority leader of the state Senate, as a top recruit, bolstered by strong fundraising so far. But McMorris Rodgers has an edge in cash on hand, reporting $1.2 million in the bank as of July 18, compared to Brown’s $920,000. Brown has also been endorsed by EMILY’s List, which backs female Democrats who support abortion rights.
