Please remember....that the Precedent before the Court decided abortion was some kind of right....was that abortion was murder. And murder was a crime.
Obama let so many cases slip by that Democrats have argued PRECEDENT to NOT enforce immigration laws.
Never let a liberal Democrat make their case by arguing PRECEDENT.
Once they can establish PRECEDENT it's difficult to get laws enforced which is why they end up in court. And if you get a liberal judge, they will accept PRECEDENT as SETTLED LAW.
