Positions
LiberalConservative
Economy & Taxes
Supports raising revenue by closing tax loopholes and increasing taxes on corporations and wealthy households, including raising the corporate tax rate, taxing capital gains as ordinary income, reforming the estate tax, and ending common tax shelters; proposes using the revenue to expand programs such as healthcare, climate action, and support for the middle class.
Healthcare
Supports the Affordable Care Act and expanding access to care through targeted government programs and reforms rather than adopting a single‑payer Medicare for All system. Focuses on expanding mental‑health services, protections for maternity and disability care, and legislation to extend ACA premium tax credits and improve coverage affordability. Opposes full single‑payer proposals while advocating government action to lower costs and broaden access.

Immigration & Border
Supports expanded legal pathways and a pathway to citizenship, defends DACA and Temporary Protected Status, and opposes aggressive or abusive immigration enforcement tactics while calling for accountability and limits on enforcement expansion. Advocates humane immigration processing, targeted foreign aid to address root causes, and has introduced legislation to redirect ICE funding and increase oversight of immigration agents.
Abortion & Reproductive Rights
Supports abortion and reproductive rights, endorses federal protections such as the Women’s Health Protection Act to enshrine reproductive choice, and opposes restrictions that limit access (including support for repealing the Hyde Amendment).
Climate & Energy
Seth Moulton supports aggressive federal climate action, including endorsing the Green New Deal and backing major clean-energy investments such as those in the Inflation Reduction Act. He advocates expanding renewable energy, carbon pricing, and ending fossil fuel extraction on federal lands while also supporting low-carbon nuclear and fusion research. His public statements and voting record emphasize climate mitigation and large-scale clean-energy investment.
Public Safety & Guns
Supports banning assault weapons and high-capacity magazines, expanding universal background checks, and enacting/strengthening red flag (extreme risk protection) laws; has called for holding gun manufacturers accountable and other ‘common-sense’ gun-safety measures.
