Your characterization of President Obama’s leadership is inaccurate. For good or bad, he vastly expanded the powers of the Presidency. He did take actions he really had no authority to take.
- He took action on DACA, establishing a Presidential power of deferral which has been ruled unconstitutional. However to keep DACA, the Supreme Court has ruled even unconstitutional actions require years of procedural hoop-jumping to reverse.
- Obama got an individual mandate passed for the ACA under the guise of it being a tax. A Single payer option would have led to a filibuster and killed the ACA.
- Obama did a non-treaty treaty with Iran, essentially side-skirting the Constitutional provisions on treaties.
- Obama committed US troops to Syria without a Congressional declaration, overriding Congressional war powers.
Obama’s philosophy of “if Congress won’t act, then I will" is brazenly dictatorial. His famous “I’ve got a phone and I’ve got a pen" to threaten Executive Orders was also outside the Constitutional order.
Obsma gave speeches. Yes. He also took actions, some going fsr beyond proper bounds.
