"Core of Conviction: My Story of Moving from Devotion to Doubt" is a 2012 autobiography by former U.S. Congresswoman Michele Bachmann, published by Sentinel (an imprint of Penguin Group). The book chronicles Bachmann's personal and political journey from her devout Christian upbringing and conservative principles through moments of doubt to her evolution as a political activist and Tea Party movement figure. It details her family background (including her parents' divorce and Catholic school education), marriage to Marcus Bachmann, their decision to foster and adopt children, and her political career from Minnesota State Senate to U.S. House of Representatives. The narrative emphasizes motivations rooted in religious conviction and opposition to issues like abortion and same-sex marriage, while covering key political battles such as criticism of the Affordable Care Act (Obamacare) and advocacy for fiscal conservatism. The memoir serves as both personal testament and political manifesto, framing her story as one of unwavering principles amid challenges, though it has faced criticism for glossing over controversies from her 2012 presidential campaign. The book sold moderately well with mixed reviews—praised for inspirational tone but criticized for ideological rigidity—and represents Bachmann's attempt to solidify her public image during a pivotal career period.
