A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Michigan utilizes an open primary system, in which registered voters do not have to be members of a party to vote in that party's primary. All candidates appear on the same ballot and a voter may only vote for candidates of one party at any primary.[1][2]
For information about which offices are nominated via primary election, see this article.

Submitted Biography: "Andrew Lorenz is a Marine Corps veteran, father of two, and lifelong Michigander running for Congress in Michigan’s 13th District. Born in Detroit and shaped by three overseas deployments, Andrew brings a steady, disciplined, and straightforward approach to public service. His time in the Marines instilled accountability, teamwork, and the belief that leaders serve the people, not themselves. After completing his service, Andrew returned home to raise his daughters and stay grounded in the community he came from. He volunteers with youth sports, supports local families, and works directly with parents, teachers, and coaches to help kids succeed. His experiences as a single father, veteran, and working-class Michigander give him a deep respect for responsibility, family, and the importance of showing up when it matters. Andrew’s campaign is focused on restoring integrity, accountability, and common-sense leadership. He believes public service should be rooted in honesty, humility, and real conversations—not hostility, division, or online theatrics. His priorities include strengthening communities, improving mental health access, addressing the opioid crisis that has affected his own family, supporting safer neighborhoods, and ensuring that everyday residents—not extremes—shape the future of the district. Andrew leads with the same principles he lived by in the Marines: be honest, work hard, and never forget the people who rely on you."
