United States Senator

Senator Chuck Schumer

John Mannion has been a tireless champion for Central New York his entire life. As a New York State Senator he has delivered for our schools, businesses, families, and the environment. His work in the legislature has lowered middle class taxes, improved the lives of people with disabilities, and protected the drinking water supply for hundreds of thousands of people. Senator Mannion is my trusted partner and we need to send him back to Albany for another term. I’m proud to support the re-election of Senator John W. Mannion." (2022)
New York State Comptroller

Comptroller Thomas DiNapoli

I’m proud to support Senator John Mannion’s re-election because he shares my commitment to openness and transparency in state government. In the Senate, and as the Chairman of the Disabilities Committee, he’s been a relentless advocate for Central New York. He’s demanded accountability from state agencies, fights for workers, and he’s one of the leading voices in Albany for people with disabilities. Central New York needs John Mannion in Albany and I urge voters in Onondaga and Cayuga Counties to join me in supporting his campaign." (2022)
