I'll never understand why so many Libs are in favor of people breaking a myriad of Federal laws or why so many Libs support politicians who willfully and knowingly ignore Federal law and/or proactively advocate breaking/ignoring Federal law. But that's what we have going on in the case of illegal immigration.
This phenomenon is particularly interesting in light of a collective mentality espouse by many Libs that the Federal government should be, in all matter of thinking, the great over lord. States and local governments in their view are not to be trusted, too prone to undue influence by local players, particularly evil conservatives. Collectively their world view places Washington DC as the omnipotent grand controller of all things in the United States.
Except! In regards those select things that are counter to their world view. Then, by all means, defer immediately to the local political ethos. After all, on these select few things it is the indigenous politician (so long as we agree with them politically) that truly understands the situation and is "compassionate".
