Interesting, isn't it. Colorado and Washington "leagalize" pot...something that's totally against federal law, and the Obama Admin, in effect, is 'just fine' with it. BUT, the Obama Admin SUES states that pass laws which enable said states to enforce federal immigration laws as written.
The present admin's arrogance with regard to the constitution and the rule of law knows no bounds...and the so-called "conservative" Supreme Court has of late proven to be no better.
