Actress Olivia Wilde’s mother, Leslie Cockburn, fell to Virginia Republican Denver Riggleman in the state’s 5th Congressional District race.

The victory put a damper on the blue wave Democrats were hoping would roll through the region on Tuesday.

Cockburn, a former journalist and first-time candidate, made headlines over the summer for statements she made about her opponent being a fan of “bigfoot erotica.”

Riggleman, meanwhile, tried to draw attention to Cockburn’s writing career — and at one point dubbed her “Alexandria Ocasio-Cortez in a scarf.”

More than 700,000 people live in Virginia’s 5th Congressional District, which includes Charlottesville.

The seat was formerly held by Republican Tom Garrett, who announced in May that he wouldn’t be running for re-election because he was suffering from alcoholism.
