He will discover that his power as President is extremely limited
Presidential power/authority is limited by the Constitution, but I do not think one would say presidential is extremely limited. It is in fact very powerful. For conservatives it should be very limited, if one uses a literal reading of the Constitution as a guide. But that is not the case as has been seen in recent years with VP Cheney pushing the concept of an unitary executive branch. Does anyone believe Mr Trump has ever been limited by anything? I would expect he would push the limits into the unConstitutional nether lands.
He has already indicated he would use EO's to achieve his goals quickly, so expect nullifying any or all Obama EO's, followed by a long series of EO's to keep Constitutional scholars awake at night trying to figure out their legitimacy.
First order of business for Congress will be repeal of ACA. Some pundits have opined they will wait for a replacement to be developed first but I suspect they will lose their sense of urgency once it has been repealed. Conservatives will promote privatization.
One thing which really amazes me about ignorant people is they do not care if their savior is wrong or does not succeed. After all he is their savior.
