The problem with California seceding though is it won't achieve anything. You guys will just be brought right back into the fold by any means the federal government has at its disposal. And seeing as how the old Confederate states are still suffering from lingering effects of the "reconstruction" after the Civil War, I don't think Californians want to risk making a bid for independence that has a significant chance of failing. So, it may suck that there is such a disconnect between California and the rest of the nation, but you guys are kinda in it for the duration with the rest of us.
Plus, you guys give people like Clinton some sense of legitimacy. Think about it: without California, Clinton would have lost the popular vote and would have had 55 less electoral votes. That would have made Trump's win look like a resounding landslide and would have provided 100% vindication for his movement. Now though, because of California, he lost the popular vote, so while he may still be president, his supporters may feel more confident but they still know they are outnumbered.
