It’s really a silly question. The President has power, it’s just not total power. Anyone could look this up.

The danger comes when you have a combination of a Republican president and Republican Senate and they’re able to load up the courts with racists.
That’s when the voting rights act gets gutted, affirmative action gets rolled back, and even if reparations got passed by the congress, it would go to the Supreme court to die.
And if the Republicans get all three branches they can control the budget and create laws as well.
Look it up for yourself.
