Domina was born in
Cedar County in northeastern Nebraska, and grew up on a farm. In 1972, he graduated from the
University of Nebraska College of Law. In 1973, he began practicing law in
Norfolk, Nebraska. From 1973 to 1979, he worked as a lawyer in the
Judge Advocate General Corps of the U.S. Army and Army Reserve. In 1982, he started his own legal practice. In November 1983, Nebraska banking regulators closed Commonwealth Savings, the state's largest industrial
savings and loan, declaring it insolvent. Two weeks later, Nebraska Attorney General
Paul L. Douglas disqualified himself from matters related to Commonwealth, and appointed Domina as special assistant attorney general to investigate the matter. The investigation led to Douglas's impeachment by the Nebraska legislature, on charges including misrepresenting his financial dealings with Commonwealth vice-president Marvin Copple, lying to the investigators, failing to disclose his conflict of interest in matters related to Commonwealth and the Copple family, engaging in insider borrowing, and failing to investigate when warned by the
FBI of financial irregularities at Commonwealth. The
Nebraska Supreme Court split 4–3 in favor of finding Douglas guilty on one of the six articles of impeachment; since five votes were necessary to convict, Douglas was acquitted. In 1986, Domina sought the
Democratic nomination in the Nebraska gubernatorial election. In the primary, he came in second in an essentially three-way race:
Helen Boosalis, the mayor of
Lincoln, won the nomination with 44% of the vote, carrying 77 of Nebraska's 93 counties; Domina received 26.2% of the vote, carrying 16 counties; and Lincoln legislator
Chris Beutler came in third, with 21.8% of the vote. Minor candidates and write-ins comprised the remaining 8% of the vote. Boosalis went on to lose the general election to
Republican candidate
Kay Orr. In 1989, Domina moved from Norfolk to
Omaha, where his firm had opened an office. In 1997, he separated from his partners in Norfolk, establishing a new firm in Omaha. ==1997–2014==
