Positions

LiberalConservative

Healthcare

Supports expanding access to health coverage, including universal coverage goals and preservation/strengthening of the Affordable Care Act with measures like a public option to broaden access and lower costs.

Immigration & Border

Dan Koh emphasizes his family’s immigrant background and frames immigrants as part of the American story, but I could not find a clear, detailed policy platform or concrete proposals on immigration or border enforcement on his campaign site or in major news coverage. Public statements available emphasize welcoming immigrant roots and sympathy for immigrants rather than specific policy prescriptions.
