Biography
Mike DeWine has spent more than four decades at the center of Ohio Republican politics. He served in the Ohio State Senate in the early 1980s, then spent nearly a decade in the U.S. House of Representatives before winning a term as Ohio Attorney General. He then served two terms in the U.S. Senate from 1995 to 2007 before losing a 2006 re-election bid in the Democratic wave that year to Sherrod Brown. He returned to Ohio, served another two terms as Ohio AG from 2011 to 2019, and then won the governor’s race in 2018 against Democrat Richard Cordray by a narrow four-point margin.
As governor, DeWine emerged as a national figure in early 2020 for his aggressive early response to the COVID-19 pandemic. Ohio was among the first states to close schools, issue mask guidance, and restrict large gatherings. Public health experts praised the early response, and DeWine’s approval ratings soared. He later faced criticism from the right wing of his own party for maintaining pandemic restrictions, and a 2020 Republican base challenger accused him of abandoning conservative principles. He survived that challenge and won re-election in 2022 by 26 points over Democrat Nan Whaley, demonstrating that even in a deeply polarized era, an experienced institutionalist could win large margins in a swing states.
DeWine is not running for re-election due to Ohio’s term limits, which restrict governors to two consecutive four-year terms. His departure will open a competitive race in 2026 in a state that has trended Republican at the presidential level (Trump won Ohio by 11 points in 2024) but has historically produced competitive statewide races. DeWine is considered a genuine moderate Republican — pro-life but more willing than most Republicans to engage with gun polling legislation and environmental concerns.
- Mike DeWine (R-OH) is the Governor of Ohio, first elected in 2018 and re-elected in 2022 by 25 points — one of the largest gubernatorial margins of victory in recent Ohio history.
- Ohio is R+8 at the presidential level — Trump won it by 11 points in 2024, and DeWine has governed as a moderate-conservative, occasionally drawing criticism from the MAGA wing for actions like supporting pandemic restrictions.
- DeWine previously served as Ohio Attorney General (2011-2019), US Senator (1995-2007), and US Representative — making him one of the most experienced politicians in Ohio history with a 40-year career.
- He is known for his pragmatic, non-ideological style — working with Democrats on gun violence, early childhood education, and addiction treatment, while maintaining conservative fiscal and cultural positions.
Key Policy Areas
Public Health
DeWine’s COVID-19 response in spring 2020 made him a national symbol of competent pandemic governance. His daily press briefings with Dr. Amy Acton, then Ohio’s health director, were lauded as models of clear public health communication. He has also invested in Ohio’s opioid treatment infrastructure and signed legislation expanding mental health services, reflecting an understanding of public health that goes beyond immediate crisis management.
Gun Safety
After the 2019 Dayton mass shooting that killed nine people in minutes, DeWine broke with most Republican governors by pushing the state legislature to pass gun polling legislation. He eventually signed a bill that included a “strong offender” sentencing enhancement and background check improvements, though gun polling advocates argued it fell far short of what was needed. His willingness to engage the issue at all set him apart from the majority of Republican governors.
East Palestine & Environment
The February 2023 Norfolk Southern train derailment in East Palestine, Ohio became a national story about rail safety and hazardous materials. DeWine was among the first officials on the ground and pushed aggressively for Norfolk Southern to cover cleanup costs and compensate residents. He signed legislation requiring improved rail safety standards and supported enhanced federal oversight of hazardous materials transport, a position that required pushing back against industry and some in his own party.

Medicare Drug Pricing & Ohio Healthcare
Governor Mike DeWine (R-OH) has governed Ohio during a period of significant healthcare policy change, including the Inflation Reduction Act's Medicare drug price negotiation provisions. Ohio's large elderly population makes Medicare policy particularly salient in the state — price reductions on 10 key drugs affect hundreds of thousands of Ohio seniors. DeWine, who has occasionally broken with national Republican orthodoxy on healthcare and other issues, has navigated a state that leans Republican at the presidential level but has competitive statewide races. His Medicaid expansion support put him at odds with many Ohio Republicans. The healthcare polling landscape in Ohio reflects a population deeply affected by drug costs and insurance access.
