The last time the left tried legitimately to amend the Constitution was with the ERA. It failed, but it didn't matter because the courts read it into the 14th Amendment in rulings such as the VMI decision. No one is bothering to propose an amendment to guarantee a right to same sex "marriage." Instead, it's taken as a given that the courts will eventually add this amendment by fiat. Instead, conservatives are trying to amend the Constitution to stop it. So we've come full circle from what our Founders intended. Instead of requiring super-majorities to change the Constitution, it's now expected that it will change automatically in a liberal direction unless conservatives can get super-majorities to keep it the same.

Though there is a list of largely symbolic proposed federal constitutional amendments, only conservatives and libertarians appear to care enough about such things to make amendments part of a unified campaign platform. That appearance is itself dubious. Any serious amendment fight would be protracted and a career-ender for many politicians from divided districts and so would never happen.
The Constitution continues to be a figurehead.
