Recognized as being an effective and bipartisan member of the Senate, Peters announced in January 2025 that he would not seek a third term, thereby making the race to succeed him in the purple state of Michigan one of the most closely watched of the 2026 midterm season.

Business, military, and political life

Out of college, Peters went to work at a number of investment firms, including Merrill Lynch and PaineWebber, where he rose through the ranks from financial adviser to vice president through the 1980s and early 1990s.

Peters was a member of the Rochester Hills, Michigan, City Council from 1991 to 1993. He then joined the U.S. Naval Reserve (1993–2000) and saw active duty in the Persian Gulf. In 1994 he was elected to the Michigan state Senate, where he served from 1995 to 2002, a period interrupted by a return to military service (2001–05) after the attacks of September 11, 2001. Peters also served as Michigan’s lottery commissioner (2003–07), worked in finance, and taught at various universities.

In 2008 Peters ran for the U.S. House of Representatives and defeated a longtime Republican incumbent to win Michigan’s historically conservative 9th district. He took office the following year. Peters typically voted with his party, and he was a strong supporter of Pres. Barack Obama’s policies, particularly the Patient Protection and Affordable Care Act. In addition, he backed raising the minimum wage and immigration reform. Peters was reelected in 2010. After Michigan lost a congressional seat following the 2010 census, he ran in the traditionally Democratic 14th district and won in 2012. When Democratic Michigan Sen. Carl Levin announced that he would not seek reelection in 2014, Peters ran for his seat and won by a large margin. He entered the Senate the following year.

Work in the Senate

Peters quickly developed a reputation for being highly effective at working across the aisle to get legislation passed. During the 116th Congress (2019–21), Peters was ranked by the Center for Effective Lawmaking as the most effective senator. He managed to get 10 bills passed into law, despite the Democrats not holding the majority in the Senate during this period. He was noted for his ability to build coalitions and win Republican cosponsors for this legislation.

In 2020 Peters became the first sitting senator to publicly share an experience with abortion. He recounted in an interview with Elle magazine how in the late 1980s, his first wife, Heidi, who was four months pregnant, was initially denied a medically necessary abortion when the fetus was determined not to be viable. Heidi Peters was granted an abortion at another hospital, but Gary Peters recounted that the experience “enacted an incredible emotional toll.” Peters went public with the story in the wake of U.S. Pres. Donald Trump’s nomination of Amy Coney Barrett to the U.S. Supreme Court.

Peters was in the U.S. Capitol preparing for the certification of the 2020 presidential election on January 6, 2021. The next day, he called Trump a “clear and present danger” and called for invoking the 25th Amendment, saying: “He continues to put out conspiracy theories, and as a result of that he’s stoking people to engage in violent activities. That’s simply unacceptable behavior for a president of the United States, and it has to lead to the question that he’s simply unfit for this office.”

In January 2025 Peters made the surprise announcement that he would not seek a third term in the Senate, telling the Detroit News: “I always thought there would be a time that I would step aside and pass the reins for the next generation.”
