Candidates in Washington state’s most closely watched congressional race have spent more than $10 million entering the final weeks of the campaign.

Meanwhile, outside forces are shelling out nearly twice as much to sway voters in the 3rd Congressional District contest that will help decide which political party controls the U.S. House in 2027.

Democratic U.S. Rep. Marie Gluesenkamp Perez, who is pursuing a third term, has raised $8.8 million and began October with roughly $640,000 on hand, according to filings with the Federal Election Commission.

Her opponent, Republican state Sen. John Braun, has hauled in $3.2 million and started October with $1.1 million available.
