In response to Kurt Weyland's optimistic assessment of American democracy, this article challenges his conclusion that the United States is immune to democratic reversal. Using a set-theoretical approach similar to Weyland's but incorporating broader structural factors like inequality and racial cleavages, we demonstrate potential pathways toward democratic backsliding.

### Contradicting Institutional Optimism

Weyland argues that institutional strength protects US democracy even amidst challenges. However, our analysis reveals these institutional dynamics alone do not fully explain away risks of democratic erosion.

### Key Critiques

* Overlooking Structural Factors: Weyland's focus on institutions misses embedded structural conditions crucial to political change.

* Methodological Concerns: His study raises issues with endogeneity, coding errors, and the use of crisp-set Boolean algebra in QCA.

* Re-evaluating Set Theory: While critiquing QCA methodology, we maintain skepticism about its overall suitability for this complex question.

### Replication Findings

Despite our concerns regarding Weyland's methods, we replicated his original analysis. Our results show the United States could potentially fit patterns associated with democratic continuity or backsliding depending on specific conditions.
