Assistant Caddo District Attorney Brady O'callaghan are both in the running for Caddo District Court judge.
They're campaigning for the special election in October.
Miller says his experience sets him apart from O'Callaghan.
"That extensive experience included domestic, civil and criminal litigation and that helped support my decision to move from advocate to decision maker," says Miller.
Miller spent 13 years in private practice, and now works in the Indigent Defenders Office in Bossier Parish.
He says becoming a judge has been on his radar for many years.
"I've always wanted to move to the next level in order to serve the public in this capacity as a decision maker to help those people who have a dispute," says Miller.
But O'Callaghan, a former prosecutor from New Orleans, also says his experience gives him the upper hand.
"I have nearly a hundred jury trials under my belt, I've protected convictions of some of our worst criminals, by going to the Louisiana supreme court keeping them on death row," says O'Callaghan.
He now works as Assistant D.A. in Caddo Parish, and he says his 10 years there speaks to his ability to serve.
