Today I learned that states can propose amendments to the US constitution. In Article V, if 2/3 of states agree, the government is constitutionally required to hold a convention to discuss amendments to the Constitution (focused on a single topic they propose). ¾ of states still have to ratify any new amendments proposed. I feel like people have forgotten about this, and it kind of seems like a cheat code to pass amendments.

This map shows state legislature control currently. Republicans have 29, Democrats have 19. 2 are split. If Republicans gained 5 states (not an easy task) they could force a constitutional convention.
