Any sort of movement for an amendment...would first require grassroot movements within each state. Only once the movement is solified in each state will it be near ready to go for an amendment.
The bar is set so high, and it should be. All these people leaning on a candidate for goals that require far more than they can accomplish on their own...is silly. These changes will require time and effort from every state, and many changes in congress. Nearly impossible with any president, actually...till the ground is fertile for change.
Sadly, it feels good to pound the chest and demand, in tones of pure righteousness, obeisance to a false premise.
