How much are you able to do without being blocked by Congress or the Supreme Court? This is a genuine question for anyone who can answer(and preferably provide good sources), I can't claim to be the most understanding of the workings of government and hear conflicting statements.

There are three co-equal branches of government. And depending who controls which while she’s there, the president is or isn’t able to do everything she’d like. No president has a magic wand - nor should they. But the power of the Presidency is still huge and hugely important. Source: the U.S. Constitution:)
