Political Positions

LiberalConservative

Economy & Taxes

Supports tax cuts and reductions in government spending, including a plan to eliminate South Carolina’s state income tax within five years and legislation to reduce or remove specific taxes (e.g., capital gains on primary residences, boat loan interest). Advocates capping state spending and using revenue growth to phase out income taxes while proposing agency cuts to meet spending targets.

Healthcare

Supports market-based healthcare and reducing federal involvement in health care decisions, arguing that competition and limited government will lower costs and improve quality. Advocates loosening federal regulations and removing taxes and penalties that she says impede access to care.

Show more

Immigration & Border

Supports enforcement-first border policies that prioritize detention, deportation, and cutting federal benefits to undocumented immigrants; sponsors and promotes legislation to increase removals, restrict benefits (including in-state tuition and federal funds for shelters), and penalize sanctuary jurisdictions. Advocates expanding resources for ICE and backing bills framed to criminally restrict entry and rapidly remove certain noncitizens, particularly those accused of violent crimes.

Abortion & Reproductive Rights

The candidate identifies as pro‑life and supports restrictions on abortion while endorsing exceptions for rape, incest, and the life of the mother. She has indicated support for gestational limits in the mid‑second trimester (around 15–20 weeks) and has criticized very early bans without adequate exceptions. She has also supported access to contraceptives and opposed efforts to let courts or individuals override FDA approval of the abortion pill mifepristone.

Climate & Energy

Supports market-oriented, conservation-focused approaches to reducing emissions while emphasizing protection of local environments and economic interests; has expressed skepticism about the settledness of climate science in the past. Has participated in Republican-led groups on climate and backed targeted measures (e.g., methane emission rules) while generally aligning with conservative energy priorities.

Public Safety & Guns

Supports Second Amendment rights, identifies as a gun owner and hunter, and has voted against federal gun-ban legislation she described as unconstitutional and ineffective. Proposes focusing on root causes of violence rather than broad firearm bans.
