Curt Clawson has defeated three other challengers in the race for Rep. Trey Radel's (R-Fla.) former House seat, the Associated Press reports.
Clawson, a self-funded Florida businessman, will face off against Democrat April Freeman in the June 24 general election.
Three other Republicans vied for the GOP nomination: Lizbeth Benacquisto, Michael Dreikorn and Paige Kreegel.
Radel resigned in January after pleading guilty to cocaine possession.
As the Associated Press notes, Clawson led the fundraising race with $2.8 million. According to Politico, Clawson put $3.4 million of his own money into his campaign. The primary was also flooded by outside groups, with $2.1 million spent mostly in attack ads.
