Political positions
The Washington Post described Granger as socially centrist, but fiscally conservative. In 2013, the National Journal, a nonpartisan organization, gave Granger a composite political ideology score of 73% conservative and 27% liberal. According to FiveThirtyEight, as of February 2020, she voted with President Trump's position on legislative issues about 97% of the time. By October 2021, she was recorded as having voted with President Biden's position on legislative issues about 11% of the time.
Granger formerly supported abortion rights and Roe v. Wade. She reversed her position in 2020, asserting that she was anti-abortion and signed an amicus brief that asked the U.S. Supreme Court to overturn Roe.
Granger's abortion reversal was especially significant given the fact that her 1996 campaign had been promoted by The WISH List, a pro-abortion rights PAC. The WISH List had also supported her 2008 campaign. Granger had received mixed ratings from groups that support legal abortion. Prior to 2020, Granger had supported embryonic stem-cell research and voted against banning chemically induced abortions. As of 2013, she supported banning abortion after 20 weeks, but asserted that abortion was not her top issue. In 2017, she declined to co-sponsor a bill to ban abortion after six weeks. Granger voted for several spending bills that included funding for Planned Parenthood, including some introduced in 2018. In 2018, she also introduced legislation banning federal funding for abortion with exceptions for cases of rape, incest, or to save the life of the woman. In 2019, Granger signed a letter to President Trump urging him to "veto any appropriations bill that weakens current pro-life protections".
Granger was known for her support for defense spending.
She voted several times in favor of an amendment to the United States Constitution to make it a crime to physically desecrate the American flag. She supported the Federal Marriage Amendment to define marriage as only permitted between a man and a woman, and also opposed letting same-sex couples adopt children. Granger was one of four Republicans in the House not to vote for or against repealing Don't Ask Don't Tell, though she had previously voted against other repeal proposals. In 2017, she said she had "no comment" in response to Trump's decision to ban transgender troops from the military. She did not vote either for or against legislation opposing the ban of transgender troops.
In June 2013, Granger was among the members of Congress to vote for an amendment to the National Defense Authorization Act for Fiscal Year 2014 to restrict the Pentagon from entering into new contracts with Russia's state arms broker, Rosoboronexport.
During her tenure, Granger supported more than $50 million in earmarks to infrastructure projects in Fort Worth that benefited the Trinity River Vision Authority, an organization led by her son.
Granger voted for a resolution supporting Israel following the October 7 attacks.
