Brad Cascio will take over the 21st Judicial District Attorney's Office, defeating Sherman Mack on Tuesday to become the top prosecutor for Livingston, Tangipahoa and St. Helena parishes.
Cascio swept all three parishes, earning 64% of the vote in Livingston Parish, 66% in Tangipahoa Parish and 54% in St. Helena Parish.
Cascio supporters gathered at a watch party in Hammond as the final results came in.
βWe did it,β Cascio said to the cheering crowd. βThere are a lot of people I have to thank for tonight.β
Mack, an attorney and former legislator, and Cascio, an assistant district attorney for the 21st Judicial District, faced each other in the districtβs first competitive district attorney race in 30 years. Cascio will succeed his boss, District Attorney Scott Perrilloux, who is stepping down after three decades in the role.
Cascio campaigned on his experience in the office, where he has worked since graduating from law school in 2013.
The race between the two Republicans was contentious and expensive, with nearly $1 million raised between them.
The candidates generated support from different corners of the stateβs political establishment. Cascio had the backing of Perrilloux, while Mack received endorsements from a litany of state elected officials, including Gov. Jeff Landry, state Sen. Valarie Hodges, four state representatives and Livingston Parish President Randy Delatte.
Cascio will now lead one of the most powerful offices in the region, deciding who is charged with a crime, who is offered a plea deal and how criminal cases are prosecuted.
