Political Positions

LiberalConservative

Economy & Taxes

As governor she has repeatedly proposed balanced budgets without broad income or sales tax increases and vetoed legislation that would raise top individual income tax rates; her budgets have relied on targeted revenue increases (for example tobacco and cannabis taxes) and spending adjustments rather than raising broad-based taxes. Mills emphasizes fiscal stability, maintaining a large rainy day fund, and using selective tax changes to address specific needs while resisting higher top income rates.

Healthcare

Supports expanding public coverage and strengthening access to care through Medicaid expansion, a state-based ACA marketplace, protections for reproductive and gender-affirming health services, and actions to defend Medicaid funding for Mainers.

Immigration & Border

Supports protections for asylum seekers and expanded state-level supports for immigrants, including creation of an Office of New Americans and efforts to expedite work authorization for asylum seekers. Has publicly opposed aggressive ICE enforcement operations in Maine and backed state legislation to limit ICE access to schools, health care facilities, libraries, and nonpublic records without a judicial warrant. Advocates accountability for federal immigration enforcement and federal policy changes to protect immigrants' rights in Maine.

Abortion & Reproductive Rights

Supports and has acted to protect and expand access to abortion and reproductive health care in Maine, including executive orders, legislation expanding who can provide abortions, insurance coverage of abortion, and legal protections for providers and patients. Has pledged to use veto power to block efforts to roll back or eliminate the right to safe and legal abortion in Maine and has supported laws putting later-pregnancy decisions in the hands of patients and doctors. Continues to join multistate efforts to strengthen reproductive freedom protections.

Climate & Energy

Janet Mills has prioritized clean energy and climate resilience as governor, advancing offshore wind procurement and planning, creating state programs for community climate resilience, and signing legislation to support at least 3,000 MW of offshore wind by 2040 while seeking protections for fishing areas. Her administration has promoted renewable energy development, port infrastructure for floating offshore wind, and state-level planning to reduce greenhouse gas impacts and prepare for extreme weather.

Public Safety & Guns

Supports expanding background checks for advertised private gun sales, strengthening Maine’s extreme-risk ("yellow flag") law to let law enforcement seek protective custody warrants in urgent cases, and tougher penalties for selling guns to prohibited persons while emphasizing protection of lawful gun ownership and public-safety/mental-health investments.

Janet Mills has effectively ended her U.S. Senate campaign in Maine, and Graham Platner went on to win the Democratic primary by a wide margin. Mills stayed on the ballot after suspending her campaign, but she drew only a small share of the vote. In the days before the primary, some supporters urged her to reenter the race as Platner faced new allegations, which he denied. Mills also recently endorsed Hannah Pingree in Maine’s Democratic gubernatorial primary.
