Season 2: Democratic Backsliding in the United States | Episode 1: The American Slide: What Democratic Backsliding Looks Like

In this episode of "The Deep Dive," we explore the subtle but urgent process of democratic backsliding, with a focus on the United States. Imagine a stressful 48-hour snapshot in August 2025, where executive power is under scrutiny. We dissect President Trump's controversial federal takeover of Washington D....

In this episode, we discuss how authoritarianism often takes root not through overt violence, but by manipulating laws and legal processes, creating a "veneer of legitimacy" for illiberal ends. This "erosion by a thousand cuts" involves concepts like executive aggrandizement, where leaders incrementally weaken checks and balances, and autocratic legalism, using constitutional and legal methods with electoral backing to consolidate ...

In this episode, we examine recent expansions of executive power in the U.S., focusing on President Trump's 2025 actions. These include the creation of "Schedule G", which aims to convert many federal employees into at-will workers, and a Supreme Court ruling granting presidents immunity from prosecution for official acts. We also detail a broader campaign to purge the civil service through mass layoffs, demotions, and public wat...

Today we examines a significant erosion of the rule of law in the United States during 2025 under the Trump administration, characterized by selective enforcement of laws and the neutering of independent institutions. We look at how the Justice Department was politicized through purges of career officials, the dismantling of anti-corruption units, and the mass pardoning of political allies. We further highlight an unprecedented c...

In this episode, we look at a significant clash between federal authority and state sovereignty regarding election administration, primarily focusing on a sweeping executive order and the Justice Department's demands for voter data. We highlight how a federal judge blocked key provisions of the executive order, such as requiring proof of U.S. citizenship for voter registration and banning the counting of mail ballots arriving aft...

Today, we examine how modern authoritarians undermine civil society by making participation in independent institutions costly, rather than outright banning them. Specifically, we highlight recent executive actions in the United States that have targeted law firms, universities, and students, arguing these actions are driven by personal grievances and an intent to suppress dissent. This approach is exemplified by freezing univers...

Today, we examine various instances where governments attempt to suppress press freedom, both domestically and internationally, often under the guise of enforcing neutral rules. We highlight how the Trump administration notably restricted media access for outlets like the Associated Press due to unfavorable coverage, leading to swift, though sometimes circumvented, judicial intervention affirming First Amendment protections. Gl...
