Packing the Supreme Court is nothing more than an emotional response and a desperate attempt to change the rules when things are not going your way. It has not worked in the past and is a bad idea. Appointing politically-motivated judges is a threat to the legitimacy of the Supreme Court, as well as the Constitution.
The Framers of the Constitution intended the judiciary to be separate and insulated from the executive and legislative branches, and the whims of politics and public opinion. They are to rule based on the text of the Constitution and the law, and not on popular political views.
The Constitution was designed to make the legislative and policymaking processes difficult so that the best ideas and laws would ultimately prevail. Court packing at the core is just a tool to bypass the legislative processes.
We must stay with basics, and the Founders’ original intent. Our elected representatives, and we as citizens, must make an earnest effort to remove partisan influences from the judicial process. That means appointing and confirming judges who are committed to interpreting the law, and leaving policy to policymakers.
