Are we at Trump’s tipping point?

No, it’s not a new opinion for me, you’ve just misunderstood. While I don’t particularly mind the authorities doing their jobs within the confines of the Constitution and while giving a reasonable good effort to comply with the various requirements, I would not welcome an investigation of me personally as it’s a hassle with very little upside. I imagine some employers in California feel similarly. Others are probably employing illegals and I imagine utterly dread ICE investigations.
