No, I'm not. I understand how the three branches of government are supposed to work. There are two dissonant sides to that story, each with their bad facts.
Article 1, Section 8 ... The Congress "To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water" but presidents now order the conduct of warfare, bomb foreign countries and support wars like the Saudi attempted genocide in Yemen while the Congress does nothing. That check and balance was abdicated and it is a very big deal.
Presidents declare wars on drugs and poverty which have had tremendous impact. Yes, the lock up the black folks Biden and Harris have been willing accomplices but Congress often goes along with such things.
Congress is now concerned about being able to impede to objectives of a President after four years of marshaling all the forces of heaven and hell to do that when the President wasn't their guy. Getting burned with your own fire is a bitch. Every time the pendulum swings and party power changes hands concerns over checking Presidential power changes sides.
Contrary to the America is evil because white men designed it crowd, the US Constitution is a good thing, or would be if it wasn't a dead letter because politicians see it as an impediment to their objectives. Constitutional separation of powers works sometimes.
Then we come to the Supreme Court which should be about the supreme law of the Republic; the US Constitution. Alas, the Supreme Court is chosen along ideological party lines and has activist Justices. How can an activist SC perform it's duties when it is about packing it with people who have an ideology that your side favors?
I'm not the least bit confused. Kamila Harris has stated that in a Harris Presidency she will give Congress sixty days to act and then she will unilaterally act with Executive power. That's a promise that she will be a dictatorial tyrant with contempt for Congress. If Biden is elected no reasonable person can doubt that he will not last four years and she will be POTUS. I hope that the Congress can exercise it's constitutional power with her at the helm, but it's a different concern than the Democrats will have once the Orange man is gone.
