Pramila Jayapal led Brady Walkinshaw in Tuesday returns for Washington’s super-liberal 7th Congressional District.

If she wins the seat occupied since 1988 by retiring U.S. Rep. Jim McDermott, Jayapal will become the first Indian-American woman elected to Congress.

The 52-year-old state senator — an immigrant-rights activist who scored an endorsement from Bernie Sanders last spring — had 57 percent in the Seattle-area clash featuring two Democrats, with 124,896 votes to Walkinshaw’s 91.036. There were 1,802 write-in votes.

The battle between Jayapal and Walkinshaw, a 32-year-old state representative, was the only competitive congressional contest in Washington.

In other districts, most incumbents were coasting to re-election, many of them having outspent their challengers by at least 10 to 1.

Jayapal easily finished first among nine candidates in August’s top-two primary election with 42 percent. Walkinshaw, who would be Washington’s first openly-gay congressperson, narrowly finished second in the primary with 21 percent.

Neither candidate was in Olympia long before choosing to run for Congress.

Jayapal was elected in 2014 to represent Southeast Seattle, Skyway and Renton. Walkinshaw was appointed in 2013 to represent Capitol Hill, Wallingford and Fremont after working for the Bill & Melinda Gates Foundation.
