"I’m so proud that Stefany is answering the call to serve the district she was born and raised in, where she has started a business, worked on the Portsmouth City Council and advocated for affordable health care and clean water," Sen. Jeanne Shaheen said
"She’s working hard to earn voters’ support in her own right and on her own merits — and I couldn’t be prouder to support her candidacy. "
Shaheen emphasized priorities like Medicare for All, expanding tax breaks for first-time homebuyers and overhauling Immigration and Customs Enforcement (ICE).
Sullivan, for her own part, pitched herself as an experienced veteran. On her campaign website, she highlighted her military service in the Marines, her work with the Obama administration in 2014 as an assistant secretary at the Department of Veterans Affairs (VA) and her leadership as a private sector health technology executive.
"I joined the Obama administration. I was proud to work on matters of national security, healthcare and reform to help fellow military families like mine," Sullivan said in a campaign video.
