Kowalko was born in Portsmouth, Virginia, to Adele and John Kowalko, Sr., a 24-year career Marine. He graduated from St. Joseph's Prep in 1963 and apprenticed at the Philadelphia Naval Shipyard. He was a machinist for over 30 years, including General Foreman at the Delaware City Refinery. Kowalko also worked as a community advocate on a range of issues, including heating assistance for low-income families.
Political career
In 2006, Kowalko was elected as State Representative for the 25th District. He beat incumbentRepublicanStephanie Ulbrich, who had been in office since 1994. In his first few years in office, he was instrumental in the push for the Delaware Offshore Wind Farm. In 2009, he was named one of Delaware Today's "People of Influence" for his work on environmental issues. He is known for being an advocate of open government and has also sponsored legislation focused on consumers, public education, public utilities, health care, and state worker pensions. He regularly testifies at Public Service Commission hearings on behalf of utility consumers. By 2015, Kowalko was known for his passionate and outspoken stances and was described as a "maverick" for being willing to publicly disagree with his own party, particularly Governor Jack Markell and other Democratic party leadership. After an attempt to remove Democratic House SpeakerPeter Schwartzkopf from his leadership position, Kowalko was taken off several committees by the Speaker for being an "activist," while Kowalko called Schwartzkopf's actions an "abuse of power." Kowalko's participation in local community meetings and strong constituent support in his district has been cited as allowing him to take on his own party leadership. Kowalko and State Senator Dave Lawson sponsored a bi-partisan bill to allow parents and their children to "opt out" of statewide standardized testing, which was supported by the Delaware State Education Association and the Delaware Parent Teacher Association. After two contentious committee hearings, the bill passed both houses nearly unanimously but was vetoed by Governor Markell. Kowalko and Lawson criticized the action and attempted the first veto override since 1977, but it ultimately failed in the House after being blocked from debate. In 2018, Kowalko described the actions of Democratic Governor John Carney as "" after Carney used an Executive Order to enact budget restructuring that failed to pass the General Assembly and was opposed by Kowalko.
