To propose an amendment to the Constitution, it can be done through the following methods:
c. By a convention called by two-thirds of the states: This method involves two-thirds (or 34 out of 50) of the state legislatures calling for a convention to propose amendments. Once the convention is held, any proposed amendments would then need to be ratified by three-fourths (or 38 out of 50) of the states to become part of the Constitution.
b. By referendum: In some cases, states may choose to hold a referendum where the voters directly decide on a proposed amendment to the state constitution. This method varies among states and is not as common as the convention method.
These are the primary ways in which an amendment to the Constitution can be proposed, emphasizing the importance of broad support and consensus among the states or the citizens.
