Goodness sakes. You really don't understand the role of the Supreme Court. Do I need to dumb this down for you to understand? The Constitution says what the Constitution says. The Judicial branch interprets the Constitution. The Legislative branch has the power to amend it. Presidents, who are elected, nominate Justices. But Congress has to ratify them. The last 2 Justices were nominated by a Republican President, but ratified by a Democratically controlled Congress. The same thing could be said for other Justices nominated by A Democrat President.
Again, if you want to amend the Constitution, then elect members of the Senate and House to meet that "popular" need. If abortion were that "popular" and important from a priority perspective, then the people would elect Congress members to change it. But right now, that's not the case. And you'll see why come November...
