This leads us to the first limit on President Trump: executive orders are only proper where they “direct that a congressional policy be executed in a manner prescribed by Congress.” The president does not have the power enact wholesale changes in domestic policy without Congress’s say.
Putting the above into practice, President Trump would not be able to wholesale remake our nation’s immigration system via executive orders. Members of Trump’s transition team have already expressed their desire for him to use executive orders to begin constructing the Huuugge Wall of America™ and to create a Muslim registry. At minimum, President Trump needs Congressional authorization to enact those policies—which is to say nothing about their ultimate Constitutionality or sensibility.
The flip side to stopping President Trump is that no president can use executive orders to wholesale rewrite domestic policy. It was therefore improper for President Obama to bypass Congress in implementing DACA. Yes, you may wholeheartedly agree with that policy, and wish the Supreme Court upheld its Constitutionality. But the price of your desired policy and an efficient system is far too high to give President Trump (or any president) such power.
