Political Positions
LiberalConservative
Economy & Taxes
Supports tax cuts and lower tax rates for individuals and businesses, including backing the 2017 Tax Cuts and Jobs Act and opposing new taxes such as a carbon tax.
Healthcare
Opposes single-payer/Medicare for All and supports market-oriented reforms to the health system, including repeal or replacement of large parts of the Affordable Care Act. Focuses on expanding access to digital health and targeted Medicare reforms (cost reductions and access in Medicare/Medicare Advantage) rather than creating a universal government-run program. Uses legislation and bipartisan initiatives to adjust program rules and reduce patient costs while preserving private insurance options.

Immigration & Border
Supports stronger border enforcement and expanded physical barriers while backing stricter immigration enforcement measures (e.g., detention and removal of certain unauthorized entrants) and reforms to limit executive parole and increase transparency about migrants released at the border. Sponsors and co-sponsors legislation to expand border-wall construction and to tighten parole and detention practices. Advocates faster removals and greater reporting/transparency of catch-and-release data.
Abortion & Reproductive Rights
Supports significant limits on abortion access, including bans on mail-order/chemical abortions and restrictions after fetal pain/20 weeks, while promoting informed-consent and conscience protections for medical providers. Advocates federal and state measures to restrict certain abortion methods and require in-person care and ultrasound information prior to abortions.
Climate & Energy
Supports expanded domestic fossil fuel production and offshore leasing, seeks permitting reform to lower energy costs, and opposes carbon taxes and EPA regulations that would force generation shifts away from fossil fuels. Advocates for government actions to boost U.S. energy production and competitiveness while favoring market-oriented measures and targeted clean-energy investments rather than aggressive emissions mandates.
Public Safety & Guns
Supports Second Amendment rights and has sponsored legislation to expand gun purchase options and limit state-level restrictions; opposes broad bans on firearms and certain federal regulations. Has also supported targeted measures with due process—such as incentives for state red‑flag/crisis intervention laws and protections in that legislation.
