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. Missouri 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.[1]

For information about which offices are nominated via primary election, see this article.

This page focuses on Missouri's 4th Congressional District Democratic primary. For more in-depth information on the district's Republican primary and the general election, see the following pages:

Submitted Biography:  "My name is Jordan Herrera and I am running for Congress in Missouri’s Fourth District because this district deserves serious leadership. I grew up in instability and violence. I learned early what it means when the systems meant to protect families fail. At nineteen, I joined the United States Air Force and served honorably for nearly sixteen years. I deployed overseas, supported missions across multiple continents, and led healthcare teams through the COVID crisis across eight states to make sure people had care when it mattered most. When I came home, my service did not end. I became an Assistant Attorney General for the State of Missouri and served six million Missourians. I have defended the rule of law, protected our communities, and worked inside government to make it work better for everyday people. I am running because leadership matters. Missouri cannot afford representatives who misrepresent the law, chase division, and serve party interests over working families. We need leaders who understand national security, healthcare, housing, and the Constitution, and who know how to deliver results. I am running to lower costs, protect healthcare, support veterans, and build an economy that works for working families. Missouri deserves leadership with integrity, experience, and the courage to act."

Key Messages

To read this candidate's full survey responses, click here.

My campaign is built around four core priorities that reflect what families in Missouri’s Fourth District are asking for. First is economic security. This means lowering everyday costs, expanding access to affordable housing, protecting healthcare, and making sure working families can get ahead with wages that keep up with the cost of living.

Second is a strong, smart national defense. National security requires a modern, ready military that protects the country while using taxpayer dollars responsibly and supporting service members, veterans, and their families. Third is freedom and privacy. Government should protect individual rights and personal liberty, including privacy, family autonomy, and equal treatment under the law, while upholding constitutional principles.

Fourth is investing in the future. Long term strength depends on education, workforce development, innovation, and infrastructure that create American jobs and prepare the next generation to compete and lead. I am running to bring practical leadership, operational experience, and a service based approach to Congress, with a focus on delivering measurable results for Missouri’s Fourth District rather than partisan conflict.
