Porter's attempts to get fetal heartbeat bills passed in American state legislatures has led to her being described as "in many ways the godmother of the heartbeat movement." Prior to founding Faith2Action in 2003, she was the legislative Director for Ohio Right to Life for nine years (1988–97). At Ohio Right to Life, she helped lobby for the first partial-birth abortion ban in the United States, which was later upheld by the Supreme Court. She then served as the national Director of the Center for Reclaiming America from September 1997 to 2002. She has said that she joined the Center because she wanted to focus on more issues than just abortion. she's also just a simpleton who literally has no proof for anything she claims, not unlike many of today's prominent right wing nuts and nationalists. At the Center, she led a campaign promoting the idea that homosexuality is an individual choice. In 2011, she played "testimony" from a fetus in legislative hearings on a heartbeat bill, by projecting an ultrasound image onto a screen and showing it to legislators.

Porter previously hosted a radio show, also called Faith2Action, before it was cancelled in 2010. VCY America, the show's parent company, said it cancelled the show because Porter had expressed views too similar to dominion theology as its host. The following week, she posted a blog post denying that she supported dominion theology.

In 2016, Porter ran unsuccessfully against Larry Obhof in the Republican primary for the Ohio Senate's 22nd district. As a candidate, she criticized her Republican opponents for not supporting her heartbeat abortion bills. Her campaign for Obhof's senate seat was supported by Mike Huckabee. In a February 2016 video, Huckabee announced that he was supporting Porter because she would fight "for faith, family and for freedom."

In 2017, she served as a spokesperson for Roy Moore in his campaign for the United States Senate special election in Alabama, 2017, drawing media attention for repeatedly refusing to answer direct questions about the candidate's publicly stated beliefs.
