Thought Experiment Theater...
In the vein of a previous post that mused about Texas independence, if a state really wanted to have more control in their affairs, the global trend is not secession, but in lobbying for more autonomy.
I've kept an eye on the California "secessionist" movement, if you even want to call it that. Yes there is one, but it's pretty realistic that secession will not work, for many of the reasons explained here:

They have the Bloc Quebecois movement and the First Nations Movements. In the 90's the Canadian Parliament got together with these groups and worked out a plan to give them more autonomy. As a result, Quebec is fairly autonomous from Canada. Sure, they share the same military, the same money and they try to share the same languages - but Quebec has the authority to take out loans, and in many cases their Provincial laws supersede the national ones.
Then let's look at Nunavut. It's an arctic region with a mostly first nations population. They are almost completely autonomous, with the exception of military and currency. The official language of Nunavut isn't even English or French - its the Inuit Language which has its own alphabet. For all prectical purposes, they have their own government - The Legislative Assembly of Nunavut which is a unicameral assembly who governs by consensus. One interesting note is that they have no political parties.
