....this is the real issue here. I don’t know much about emission regs in Cali other than that they always seem to be the most strict and sometimes are claimed by engineers to be unattainable. Maybe so, maybe not.
But the idea of a state choosing which federal laws to follow and which to ignore is very detrimental to our country. You can imagine how this could play out elsewhere on various issues.
Right now, the real battle is not just the particular issue. The Left hates Trump, and far left states are pushing the legal limits of “resisting” to their breaking point. I promise that they won’t like it if say Indiana decides not to recognize a liberal federal law.
