What amendment would you like to see? --- Here's the process for amending the Constitution: Congress may submit a proposed constitutional amendment to the states, if the proposed amendment language is approved by a two-thirds vote of both houses. Congress must call a convention for proposing amendments upon application of the legislatures of two-thirds of the states (i.e., 34 of 50 states). Amendments proposed by Congress or convention become valid only when ratified by the legislatures of, or conventions in, three-fourths of the states (i.e., 38 of 50 states). Those are very high hurdles. Do you see why it is difficult to change the Constitution?
