Which clause in the U.S. Constitution explains the limited number of amendments since 1787?

The Elastic Clause, also known as the Necessary and Proper Clause, is found in Article I, Section 8 of the U.S. Constitution. It grants Congress the authority to make all laws that are necessary and proper for carrying out its enumerated powers. This clause suggests that the framers of the Constitution deliberately left certain powers open to interpretation and expansion, allowing for future adaptations and amendments.

Regarding the limited number of amendments since 1787, the Elastic Clause indicates a flexibility in governance. While the Constitution allows for amendments to be added, the Elastic Clause reflects the broader principle that the government can adapt to changing circumstances without needing to amend the Constitution for every situation. This inherent flexibility may result in fewer formal amendments, as Congress can legislate on a wide range of issues within its scope of power.

The other clauses mentioned, such as the Equal Protection Clause, the Establishment Clause, and the Supremacy Clause, do not specifically address the process or rationale for the limited number of amendments but focus instead on civil rights protections, the relationship between state and federal laws, and the role of federal laws in context to state laws, respectively.
