Think about this; these are the same people who want an open border with Mexico and all 120 million Mexicans should be allowed vote,, so what they are really saying with succession is California should be annexed by Mexico.
Maybe they don't really want that -- and that's why they won't secede.
When it comes to politics, people love to strike poses, but they rely on their opponents to prevent what you might think they want from ever happening.
Same thing in Arizona. Tucson loves to slam Phoenix, but at heart they recognize that it's all for show.
