"The Democratic Party remains committed to equal protection under the law for all Americans. How we achieve that goal continues to be the subject of a contentious debate, but our party continues to oppose constitutional amendments that seek to short circuit the debate on how to achieve equality for all Americans."This is how the Democrats see things. If the right manages to get the constitutionally required supermajority of Congress and supermajority of the state legislatures to affirm one side of a contentious issue, that's not settling it; it's "short-circuiting the debate". But when the left manages to get five unelected Supreme Court justices to affirm their side of a contentious issue, that produces settled law.
