LEFT-CENTER BIAS

These sources are generally trustworthy for information, but may require further investigation. See all Left-Center sources.
- Overall, we rate The Preamble as Left-Center Biased due to its consistent criticism of conservative positions and generally favorable framing of progressive social policies. We rate its reporting as High for factual accuracy, based on proper sourcing, the use of credible primary materials, and a balanced, educational presentation of opposing viewpoints.

History
The Preamble is a daily newsletter created by Sharon McMahon, a former government and law teacher known as “America’s Government Teacher” on social media. It launched in September 2020, following McMahon’s viral video that corrected misinformation about the Electoral College. Based in the U.S., the newsletter offers historical context and nonpartisan insights to help readers understand how government and politics work. McMahon’s mission is to foster critical thinking, not partisan division, guided by her belief that “the world needs more contributors, not more critics.”

Analysis / Bias
Based on our review of recent articles, The Preamble shows a left-center bias and has an educational, explanatory tone. The outlet tends to critique conservative policies more sharply than liberal ones, although it consistently makes efforts to include multiple viewpoints.
To evaluate this, we examined two representative examples of its work.
First, in Is DEI Discrimination? Here Are the Arguments on Each Side the publication discusses the Trump administration’s decision to cut federal funding from organizations that continued DEI programs, contrasting it with the Biden administration’s support for such initiatives. The article draws from well-sourced materials, including Chalkbeat, the Department of Education, Whitehouse.gov, The New York Times, ProPublica, and Oyez (Supreme Court case summaries), and all are properly hyperlinked. It presents both sides of the DEI debate by citing opponents’ claims of reverse discrimination, quoting Ibram X. Kendi (pro-DEI) and Heather Mac Donald (anti-DEI). While the reporting remains fact-based, the framing subtly favors pro-DEI perspectives and critiques the Trump administration’s policies more directly than those of Biden’s.
Second, in The New Enemies List” by guest author Andrew Kordik, the site critiques the Heritage Foundation’s Project Esther, which it argues equates pro-Palestinian views with antisemitism and advocates government suppression of dissent. The article references Anti-Defamation League (ADL) statistics (verified as accurate though not hyperlinked), it cites historian Richard Hofstadter’s work, “The Paranoid Style in American Politics,” and reviews a report from Heritage Foundation.
The tone of the article is left-leaning, using phrases like “parallel universe stuff,” “dangerously loose classification,” and “state suppression.” It compares Heritage’s approach to McCarthyism. Although the article briefly acknowledges President Biden’s strong support for Israel, it focuses more on the perceived excesses in Heritage’s framing.
In conclusion, the Preamble maintains factual sourcing and educational framing but exhibits a consistent left-center orientation, especially in its coverage of social policy and conservative institutions.
