That’s not how the amendment process works. They’d need a 2/3 majority vote in both the House and the Senate to launch a proposal or 2/3 of the states to hold a constitutional convention; once the amendment is proposed, 3/4 of the states would have to ratify it.
Besides, even a simple majority requirement wouldn’t guarantee success - for example, see the clown show for the GOP House speakership, Senators Manchin (I; D before 2024) and Sinema (I; D before Dec 2022) voting no on various Democratic initiatives, or Senator McCain (R) voting no on the ACA repeal.
There was actually a point where we were two state governorships away from the GOP being able to hold that convention, but that’s still just the proposal.
What a waste of chassis space.
