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. Pennsylvania utilizes a closed primary process. Voters are required to register with a political party to vote in the primary election.[1]

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

Submitted Biography:  "I am a proud American by choice, deeply committed to upholding the foundational principles that make this nation exceptional: liberty, integrity, and opportunity. Originally from France, my love for America inspired my journey to citizenship and my dedication to public service. In 2018, I proudly became the first immigrant and naturalized citizen elected as an alderman in Crestwood, Missouri, embodying the promise and possibility of the American dream. My experiences as an immigrant have only deepened my appreciation for America's unique values, fueling my resolve to protect our nation's prosperity, sovereignty, and security. With more than 25 years of professional experience in technology leadership and agile project management, I bring practical solutions and a clear vision rooted in accountability and transparency. I believe in an America-first approach—prioritizing our families, small businesses, energy independence, strong borders, and national defense. As a political analyst featured internationally, I've consistently stood firm in advocating for policies that place the interests of American citizens ahead of special interests and career politicians. My mission is to restore trust in government through honest representation and legislation that respects our Constitution, empowers American families, and preserves the greatness of this country for future generations."

Prosperity and Security for American Families: I am committed to America-first policies that strengthen our families, small businesses, and communities. I'll advocate for energy independence, secure borders, robust defense, and healthcare solutions that empower individuals—not bureaucracies.

Transparency and Trust in Government: I will champion transparency and accountability, eliminating backroom deals to rebuild public trust. Government must serve the people openly, honestly, and responsibly.

Citizen-Led Government: To restore faith in our institutions, I will fight for term limits, fresh leadership, and a government truly accountable to the people—not career politicians or special interests.
