BROOKLINE, Mass. (AP) — Kitty Dukakis, the wife of former Massachusetts governor and Democratic presidential candidate Michael Dukakis, who spoke openly about her struggles with depression and addiction, has died. She was 88.

Dukakis died on Friday night surrounded by her family, her son, John Dukakis, said on Saturday by telephone. She fought to make the world better, “sharing her vulnerabilities to help others face theirs,” her family said in a statement.

“She was loving, feisty and fun, and had a keen sensitivity to people from all walks of life,” the family said. “She and our dad, Michael Dukakis, shared an enviable partnership for over 60 years and loved each other deeply.”

Dukakis won high marks as a political campaigner during her husband’s 1988 presidential efforts, stumping tirelessly for him. She was called a key influence in his decision to seek the presidency.

Current Massachusetts Governor Maura Healey called Dukakis “a force for good in public life and behind the scenes,” a leader in the effort to ensure that the Holocaust is never forgotten, and an advocate for children, women and refugees.

Dukakis and her future husband met while attending high school in Brookline, Massachusetts, a Boston suburb. He was dull and frugal; she was dramatic and fancy. He is Greek Orthodox; she was Jewish.

By the late 1990s, Dukakis and her husband divided their time between Massachusetts and California, where she was a social worker and he was a professor for part of the year at the University of California, Los Angeles.
