Sherman Mack, a former Louisiana state representative, has announced his plans to run for district attorney of the 21st Judicial District, which covers Livingston, St. Helena and Tangipahoa parishes. The current district attorney, Scott Perrilloux, is not seeking re-election after serving five terms.

Why it matters

The race for district attorney is an important one, as the DA plays a key role in setting criminal justice priorities and policies for the region. Mack's background as a legislator and attorney could make him a formidable candidate.

The details

Mack, a lifelong resident of Livingston Parish, has 25 years of experience in civil and criminal litigation. As a state representative, he served as the chairman of the Louisiana House of Representatives Criminal Justice Committee. In his campaign announcement, Mack said a district attorney 'must be firm when necessary, compassionate when warranted, but above all honest and devoted to the people.' Assistant District Attorney Brad Cascio is also running for the position.
