The Elastic Clause, also known as the Necessary and Proper Clause, is a clause in the U.S. Constitution that grants Congress the power to make any laws necessary and proper to carry out its other powers and duties.
A strict interpretation of the Constitution would hold that the Elastic Clause should be interpreted narrowly, and that Congress should only be allowed to exercise powers that are specifically granted to it in the Constitution. This view would argue that the Elastic Clause should be used sparingly, and only when absolutely necessary.
A loose interpretation of the Constitution, on the other hand, would argue that the Elastic Clause should be interpreted broadly, and that Congress should be allowed to exercise a wide range of powers that are necessary and proper to carry out its other powers and duties. This view would argue that the Elastic Clause should be used more frequently, and that Congress should be given greater flexibility to address new challenges and changing circumstances.
