If we take him literally, ILLEGAL immigrants are going to be deported, (which most citizens support) PUNATIVE, JOB-KILLING, AND UNNECESSARY environmental regulations are going to be gutted, global warming WILL HAVE TO BE PROVEN WITHOUT THE USE OF DOCTORED TEMPERTURE DATA, POTENTIAL Muslim IMMIGRANTS will be required to prove they are not terrorists or terrorist sympathizers, NATO countries are going to have to pick up more of the cost of their defense, and trade agreements are going to be challenged to make them more favorable AND LESS DAMAGING to the U.S.
The economy will be the deciding factor as to whether or not Trump is re-elected.  If people are working, if immigration is lawful, if our national security and relationships with allies improve, Trump will win re-election.  This is what progressives really fear will happen because it will undermine the progressive/socialist agenda.
