Analysis / Bias
Kinzinger’s Substack combines personal reflection with political analysis, grounded in his experience as a former Republican who has become an outspoken critic of Trumpism. In “Trump Exploits Red State Anger (Again)”, he criticizes the administration for politically motivated funding cuts targeting Democratic areas, citing policy data and social science research to contextualize the “rural resentment” divide.
His essay “The President in Decline: Trump’s Mind, His Myths, and the Machinery Around Him” portrays Trump as cognitively declining and surrounded by extremist advisers, referencing factual public reports and incidents such as the AI-generated “med bed” hoax video to highlight misinformation.
In “Today, I’m endorsing Joe Biden”, Kinzinger frames his support for Biden as a defense of constitutional democracy over party loyalty.
The tone is consistently anti-authoritarian and critical of Republican extremism but avoids overt partisanship toward progressive or socialist causes. Kinzinger maintains a conservative ethos emphasizing ethics, patriotism, and institutional preservation. His arguments rely on documented political developments and mainstream reporting, showing clear opinion-based bias but limited emotional or conspiratorial language. The publication’s slant arises from its focus on defending liberal democracy against authoritarian tendencies within the GOP, placing it in the Left-Center range.
