The current minority party in the Congress has flatly refused to work with the opposition to craft solutions acceptable to both. In a recent prominent example, Senate Minority Leader Schumer has made it clear that they will support no revision to existing immigration lay, even in the face of compromises offered by Republicans, and that they prefer to let the President attempt to deal with the contradictions in that law for their own partisan reasons. (I believe that effort will backfire in them later, but Schumer's statements make his intransigence quite clear.
This stuff accelerated during the Obama Administration when the Democrats pushed through an unread Obamacare bill rejecting any and all requests for discussions, compromise or amendment from Republicans. Now the shoe is on the other foot.
The last two Supreme Court Appointments made by Democrat President Obama involved nominees selected by him who he believed would advance Democrat political Goals. Do you believe that Republicans should now behave differently?
The recent decisions of the Supreme Court make it very clear that there is indeed discussion and dissent within the court. That will continue even after Justice Kennedy's replacement is confirmed.
Constitutional amendments are easy to advocate but hard to get. The one you propose has extremely little chance of adoption, even in the unlikely event that it is even submitted.
