The argument from the left is it is not necessary to enforce the law. For the left the law is a virtually infinite body of legislation that can be tailored to fit the interests of the day. This is not law. It is the foundational principle of tyranny.
The good news is that under this President, the Left is looking at jail time. That should change their views considerably.
When the smoke clears, either the republic or the Obama/Hillary/Deep State conspirators and coup plotters will remain standing.
