It has worked out just fine. Trump has not done anything that he is not entitled or has power to do. That’s fact.

Presidents can issue executive orders. That is why every president comes into office and immediately changes the executive orders of the previous president. However, executive orders are not legislative laws, only congress can push that. That’s why when Lincoln issued an executive order to abolish slavery in 1863 it didn’t mean much, and people still owned slaves. However, in 1865, once it was passed as a legislation and added to the constitution, it became an official law of the land. ...that’s check and balance. There is no way around it.

2/3rd of Congress will always have more power than the president when it comes to declaring wars, issuing laws, etc . A president cannot engage the country in an armed conflict nationally or internationally without consent of congress. So this I am king over the states is just pure verbiage. The states created the federal government by forming a union, not the other way around.
