Sadly, the Feds are too busy violating the Constitution to enforce it
Not all states are like yours, or Colorado, or Connecticut, or California, or New York, to name a few.
But as sanctuary cities go, the Feds have given tacit approval or they'd cut every dime of funding until they got back in line. Why the Feds might even secure the border. Maybe they'd remove the infringements they have heaped upon the RKBA.
But, frankly, until the people in our governments (at all levels) quit viewing the Constitution as an impediment instead of the supreme law of the land, that isn't going to improve.
So, why do you stay in Illinois?
First thing you've said that I totally agree with (and it also explains why repealing the 17th amendment won't magically "restore our Republic" as long as state and local governments are run by corrupt scumbags that as bad OR worse than their federal counterparts)
