Brunswick – Government reform advocate and Brunswick resident, David Costello, announced today that he is entering the race for the United States Senate. 


A native of Old Town, Costello returned to Maine in 2019 after having served as a senior aide to the mayor of Baltimore and governor of Maryland and having helped to manage Maryland’s environmental protection agency (MDE). Prior to working in Maryland, Costello worked largely overseas for the U.S. Government, responding to political, economic, and humanitarian crises in Cambodia, Haiti, Bosnia, Croatia, Serbia, and Kosovo. 

Costello said that he has decided to run for the U.S. Senate because, “like many Mainers, he’s grown tired of the level of acrimony and dysfunction in Washington and Congress’s inability to act and to act in ways that serve the best interests of all Americans.” 


“For generations,” Costello added, “we Americans have labored to establish a more just, secure, and prosperous nation.  And while we’ve made considerable progress over the years, we have yet to establish the kind of more perfect union envisioned by our most thoughtful founders and descendants.” 


Costello contends that “we have fallen short, in large part, because our governing infrastructure is as outdated as many of our roads, ports, and bridges. Partisan gridlock, government ineffectiveness, and political disinformation abound, and our imperfect democracy is in danger of becoming even more flawed.” 


“To fix Washington,” Costello argues “we need to do more than simply changing who we elect every two to six years. We need to think bigger and act boldly to substantially reform our governing practices and institutions, and eliminate the excessive and corrupting influence that money, wealth, and misinformation have over our politics and government.”


Costello further added that he is running because he wants “to help in advancing long overdue legislative and constitutional reforms.  Reforms that will not only aid in strengthening our democracy, government, and economy, but also help in protecting our rights and freedoms, and assist in addressing such pressing problems as climate change, uneven economic prosperity, inadequate health insurance, shoddy infrastructure, underperforming schools, and insufficient retirement security.” 


Costello, a democrat, attended the University of Maine in Orono and is a graduate of the George Washington University and London School of Economics and Political Science.  For more detail on Costello’s ambitious reform agenda and policy priorities visit
