“You can’t change the Constitution with a minority!!! 2/3 of the states must ratify any changes to the Constitution!!”
No, 2/3rds of both the House and the Senate are necessary to submit amendments to the states (67%) but 3/4ths (75%) must ratify.
And to answer your other question, no states can’t just submit amendments to each other. They must come either from the Congress or from a Convention.
However, one of the amendments in Mark Levin’s book makes just this suggestion, an amendment to the Constitution to allow individual states to submit proposed amendments for other states to consider.
No, 2/3rds of both the House and the Senate are necessary to submit amendments to the states (67%) but 3/4ths (75%) must ratify. But if 3/4 the States call for a convention then the House and Senate don’t have a say!!!
