There is a common theme that I am noticing having watched the first two debates, and that is the issue of "court packing."
I find the framing of the question to be very interesting in the sense that it implies something improper on the part of trying to restore balance to our nation's court system. During the final two years of the Obama presidency, the Republican Senate only confirmed 20 judges leaving 89 vacancies including the infamous Merrick Garland nomination to the Supreme Court.
He didn't even get a hearing in committee much less a vote. Many of those same Republican senators have confirmed 181 of President Trump's nominees, including seven judges rated "not qualified" by the American Bar Association. I would suggest that the Republicans have packed the courts with radical partisans from the Federalist Society and that this is detrimental to the credibility of our court system and the principle of equal justice under the law.
I think that it is totally appropriate for the Democrats to look into the unpacking of our court system that has been carried out by Mitch McConnell and his fellow Republicans over the past six years. It would be a good thing to decrease the influence of justices and judges who were appointed based upon their commitment to party and ideology over the rule of law. Perhaps some restructuring of our court system, in order to achieve that goal, isn't such a bad idea.
