Immigration & Border
Opposes state programs that prioritize benefits for non‑citizens and criticizes federal ‘open border’ policies; frames migrant-related state spending as unfair to American citizens. Public statements call for ending programs that he views as prioritizing non‑U.S. citizens over residents of Oregon.
Abortion & Reproductive Rights
Supports pro-life policies and believes life begins at conception; favors laws that limit abortion access while promoting adoption and supports measures to restrict late-term abortions and other limits that reflect majority views.
Climate & Energy
Supports removing green-energy mandates that he says raise energy costs, emphasizes reliable low-cost baseload power (hydroelectric and nuclear), and prioritizes forest management and reduced regulation over progressive climate mandates. Advocates for market- and reliability-focused energy policy rather than aggressive emissions regulation or rapid fossil-fuel phaseout.
Public Safety & Guns
Opposes major new gun regulations and ballot/legislative actions that implement Measure 114 or raise age/permit requirements; frames proposed bills as unconstitutional and harmful to law‑abiding gun owners while supporting law enforcement and tougher public safety measures.
