Cinde Warmington won the uncontested Democratic nomination for New Hampshire governor on Tuesday evening, setting up a rematch bid against Republican incumbent Kelly Ayotte in the November general election. The nomination has renewed scrutiny of Warmington's past legal work for Purdue Pharma, the maker of OxyContin, with the Republican Governors Association branding her connection to the opioid manufacturer "disqualifying" and accusing her of prioritising a payday over New Hampshire families.

Warmington has pushed back on the criticism, saying her role as an attorney assigned to a Purdue case in 2001 was limited and that she was unaware of the company's fraudulent conduct at the time, which only emerged through later litigation; she has also spoken publicly about her own father's struggle with addiction. Purdue Pharma agreed to pay a $7.4 billion settlement in May over its marketing of OxyContin. This marks Warmington's second run for governor after losing the 2024 primary to Joyce Craig, who went on to lose to Ayotte 53.6% to 44.3%; Warmington has centred her 2026 campaign on affordability, immigration policy, housing and tax cuts ahead of the 3 November election.
