In Austin however, I've found someone I know I can trust to legislate according tot he principles of liberty, who will always give a straight answer to his constituents, and will remain firmly loyal to the Constitution. I'm proud to endorse Austin Petersen as the next U.S. Senator from Missouri."

Austin has my full support, and I look forward to him championing the cause of freedom in the U.S. Senate."
Representative Mark Matthiesen- “Austin Petersen is a principled man who believes that local communities and personal virtue always solve more problems than big government. I've worked diligently in the Missouri legislature to protect our citizens and their rights, and Petersen and I share a sense of duty to the people of Missouri. His value system will not be shaken, even under pressure. I'm proud to join my esteemed colleague Dr. Neely in endorsing Austin Petersen for U.S. Senate."

Kassy Dillon- "Austin Petersen's vision for America is rooted in a profound respect for the Constitution. With Democrats constantly turning to radical socialist policies, Austin's dedication to liberty, small government, and fiscal responsibility is desperately needed in the U.S Senate. I am grateful for his continued fight for constitutional principles, and look forward to him joining other like-minded conservative leaders in 2019."

I have yet to meet any of the other leading candidates at any of the Lincoln Day events or elsewhere,” stated Neely. “His grassroots support is growing. Missouri needs an honest, principled, hard-working representative in Washington, D.C. I believe Austin is that leader and enthusiastically endorse him in the upcoming GOP primary.”
Joshua Feuerstein- "A candidate has to be rock solid on three issues to earn my endorsement: protecting life, religious liberty, and our second amendment. In the Missouri U.S Senate race, there is one candidate with a proven track record of relentlessly fighting for these ideas, and that candidate is Austin Petersen. I want to take this opportunity to proudly and publicly endorse his candidacy to challenge leftist Democrat Claire McCaskill this November."
