But instead, he'll be singing.
Brat's campaign, along with the music-loving, conservative group #LibertyKaraoke, will host a karaoke night for supporters in Washington, D.C., next Thursday.
For as little as $20, Brat fans can croon the night away with the potential congressman, according to the event Facebook page.
"Dave Brat stunned the Washington Establishment by defeating Majority Leader Eric Cantor in the Republican Primary last Tuesday. Now it's up to grassroots activists to help him make it across the finish line in November," the page says. (It notes that the event is "private" and a contribution is required for entry).
Brat isn't the first politician to try to boost his chances on Election Day by warbling a tune or two.
Congressman Thomas Massie, R-Ky., reportedly raked in nearly $4,000 at a #LibertyKaraoke fundraiser in March (though he refused to sing).
And Igor Birman, an ultimately unsuccessful Republican candidate for California's 7th Congressional District, raised funds at a #LibertyKaraoke event in April.
Though the group has caught some flak for its raucous parties, it claims it has raised more than $20,000 for "pro-liberty" congressional candidates.
