Secession From States

Recently, I have heard a lot about counties in California and Oregon wanting to secede from their respective states and form a new state, the state of Jefferson. This was really interesting to me, because it's not everyday that a new state joins the US, and I decided to look up more about the issue. Apparently, many counties across the United States are discussing secession. In Colorado, counties have set dates to vote on whether to pursue secession or not, while in Northern California, 2 counties have officially voted to pursue secession from the state. Momentum is growing for counties in southern Oregon and western Maryland to do the same. While the secession attempts are almost certain to be rejected, as Congress and the state legislatures both have to approve the move, they do draw attention to the divide between conservative and liberal parts of some states. Almost all of the counties attempting secession are conservative and feel underrepresented and ignored by the far away liberal state governments. But, there is always the chance that Congress and the respective states do feel that the counties are right and that the states are too big to so their job correctly or that he counties are too disconnected from the rest the state, so the 51st state may not come from Puerto Rico or another place outside the country, but instead from inside the continental US. It is another example of how divided the US as a whole is. If individual states are feeling the split between liberal and conservative ideologies to the point where people are trying to form their own state, how far will the divide in the United States go?
