Existing studies may have underestimated presidential unilateral power. This article shows Congress consistently exerts veto power over federal regulations, even when the president endorses them.
Data & Methods
The research tests two models: one assuming Congress can execute a legislative veto; another requiring presidential coalitions for congressional influence.
Key Findings
- Applying empirical tests reveals consistent evidence of Congressional veto power.
- This holds true even over actions the President endorses.
Why It Matters
This finding challenges conventional understanding by demonstrating:
- The limitations on presidential unilateral power are more significant than previously acknowledged.
- Congressional influence extends beyond statutory constraints.
The article concludes that this evidence suggests existing studies may significantly understate constraints on presidential power.
