In 1978, Hagan became chairman of the
Cuyahoga County Democratic Party, beating
Garfield Heights ward leader Henry S. Trubiano. In that position, he became one of the first Democrats to endorse
Edward M. Kennedy in the
1980 presidential election over the sitting Democratic President
Jimmy Carter. Prior to his endorsement, Hagan had been a guest of Kennedy at his home in
Hyannisport. Hagan was appointed Cuyahoga County's county recorder, but he failed to keep the seat in an election. He then ran for a seat on the Cuyahoga County board of commissioners, losing to Republican Virgil Brown. He ran again in 1981, this time successfully. Hagan served on the county commission for 16 years (1982–1998).
In 1989, Hagan made an unsuccessful attempt for the office of
mayor of
Cleveland, losing the Democratic primary to Ohio State Senator
Michael R. White, who went on to defeat Cleveland City Council President
George L. Forbes in the general election. In 1992, with White's endorsement, Hagan made an unsuccessful bid for a seat in the
U.S. House of Representatives, losing in the Democratic primary to incumbent U.S. Rep.
Mary Rose Oakar. Hagan described himself as an avowed
liberal, ingrained by his father's politics, and expressed regret at the
conservative trend in the Democratic Party in the 1990s. He was known to quote
Albert Camus in his speeches, a habit that did not earn him the affection of
blue-collar voters. However, he allowed for compromises with his innate liberalism, agreeing to go along with government funding for the
Cleveland Gateway project, which included the construction of
Jacobs Field and
Gund Arena. Hagan has received praise from both sides of the political aisle. Republican
Jim Petro, the
state auditor and former fellow county commissioner, called him "the most honorable politician I've ever known". He even earned the friendship of former rival Forbes, who, during the 1989 election, had described Hagan as a "
pimp". Hagan ran into political trouble when it was revealed that Cuyahoga County Treasurer
Francis E. Gaul (famous for saying that "Most people in Cleveland think Camus is the whale at
SeaWorld," in reference to Hagan) had made risky investments using county funds, having assured the Board of Commissioners that the Secured Assets Fund Earnings fund was free of risk. Hagan was called as a witness for the
defense in Gaul's trial, saying that he had "implicitly" trusted Gaul's reassurances that the investments were safe. It was 1994, however, and the booming economy mitigated the county treasury's losses and Hagan managed to win re-election to the board of commissioners. In 1996, Hagan announced that he would retire from electoral politics after his term expired at the end of 1998, stating: "I'm in the twilight of a mediocre career. But I'm looking forward to going to the grocery store without someone asking me for a job." ==Personal life==
