Their shot at this seat
Given the significant fundraising gap and the state's Democratic-leaning structural tilt, Sununu faces an uphill climb that would require a massive shift in voter behavior to overcome.
Who's behind them
Sununu is successfully leveraging institutional GOP backing to maintain a visible and well-funded campaign presence.
What could go wrong
Sununu’s long absence from public office combined with outstanding ethics questions creates a significant credibility gap he must overcome to sway skeptical voters.
Why they fit this seat
The combination of an open seat and voter frustration with political temperature makes this an opportune moment for a traditional, recognizable Republican candidate to regain ground.
Key contrasts
opposes middle-class tax hikes, focuses on affordability
tax cuts for working families, opposes corporate interests
Who this moves: Voters concerned about affordability and cost of living in New Hampshire.
