Beavers has represented the
Wilson County Commission (1990–1994), in the
State House of Representatives (1994–2002), and in the State Senate (2002–2017). Lieutenant Governor and Speaker of the Senate
Ron Ramsey credited her first election to the State Senate as the beginning of the conversion of the suburbs of
Nashville from
Democratic allegiance to Republican allegiance. Former Democratic State Senator Bob Rochelle attempted to reclaim his seat and ran against Beavers in the 2006 general election, yet Beavers prevailed with approximately 58% of the vote. In 2010, Beavers defeated her long-time political rival, State Representative Susan Lynn, in the 2010 Republican primary, and defeated Democrat George McDonald with approximately 63% of the vote in the general election. Beavers opposes abortion and supports gun rights. She supported President
Donald Trump's
travel ban, supports the abolition of state income taxation, and is a proponent of tougher laws and measures against
illegal immigrants. Beavers has also supported legislation in opposition to the Supreme Court's
ruling on
same-sex marriage. In 2014, Beavers was rated by the
Sunlight Foundation as the second-most conservative state senator in Tennessee, behind then-senator
Stacey Campfield. She also leads the Wilson County Conservatives. Beavers is a member of the
National Rifle Association of America and a lifetime member of the Tennessee Firearms Association.
Sponsored legislation Beavers was a proponent of the Tennessee Women's Ultrasound Right to Know Act, and sponsored SB 1769, SB 775, and co-sponsored SB 632, Both bills failed to pass. Beavers opposed the 2010
health care reform legislation proposals, including the
Patient Protection and Affordable Care Act, sponsoring instead the Tennessee Health Freedom Act to protect "a citizen's right to participate, or not participate, in any healthcare system". In September 2015, Beavers proposed bill SB1437, known as the Tennessee Natural Marriage Defense Act, to ban same-sex marriage in Tennessee despite the Supreme Court's decision to legalize it. Her colleague in the House,
Mark Pody, proposed a similar bill. Had the bill passed, it would have cost Tennessee upwards of $8.5 billion in federal funding, in addition to millions of dollars in legal bills, mostly impacting programs that support Tennessee families in need such as the Supplemental Nutrition Assistance Program (SNAP), and Temporary Assistance for Needy Families (TANF). In the next legislative session, Beavers and Pody reintroduced the bill, with specific language that no court decision (presumably including those of the
Supreme Court of the United States) would affect it. ==2018 gubernatorial and mayoral elections==
