LEFT BIAS
These media sources are moderate to strongly biased toward liberal causes through story selection and/or political affiliation. They may utilize strong loaded words (wording that attempts to influence an audience by appealing to emotion or stereotypes), publish misleading reports, and omit information that may damage liberal causes. Some sources in this category may be untrustworthy. See all Left Bias sources.
- Overall, we rate Jess Piper’s Substack as Left based on consistently ideological framing, story selection, and advocacy-driven commentary aligned with progressive politics. We also rate it Mostly Factual, as the content is generally grounded in real events and accurate context, but is heavily opinionated, one-sided, and reliant on emotive language with limited sourcing and balance.

Analysis / Bias
Jess Piper’s Substack is an opinion and advocacy platform rather than a straight news outlet. Content is written exclusively from Piper’s personal perspective and consistently advances progressive political viewpoints, particularly on immigration enforcement, Republican political actors, and social justice. The writing frequently employs emotionally charged language, moral absolutism, and explicit value judgments, framing conservative figures and institutions in a strongly negative manner.
For example, the essay “Say Her Name” presents a graphic, first-person account reacting to a Minneapolis shooting involving ICE. The piece characterizes the incident as a “state-sanctioned execution” and explicitly condemns ICE and the Trump administration using vivid language and personal reflection. While the article is rooted in a real-world event, it does not present official statements, alternative interpretations, or a balanced context; instead, it prioritizes emotional impact and political advocacy.
Similarly, “Excusing Abuse as Political Strategy” offers a sharply critical analysis of Megyn Kelly and the Republican Party in response to commentary surrounding the Epstein emails. The article relies on selective quotations, strong moral framing, and generalized conclusions about Republican voters and leadership, reinforcing a consistently left-leaning editorial stance.
Additional content, such as “Feed Kids. Fix Roads. Fund Hospitals.”, promotes Democratic candidates and progressive policy priorities through favorable, endorsement-style coverage. This reinforces the site’s role as a political advocacy outlet rather than a neutral analytical source.
Across the Substack, sourcing is often narrative-based, with limited reliance on primary documents or neutral third-party reporting. Hyperlinks are primarily used to reference aligned individuals, organizations, or campaigns rather than to substantiate claims with diverse or opposing sources. Overall, the newsletter prioritizes persuasion, mobilization, and moral argumentation over balance or traditional journalistic standards.
