That can happen, true. But, if these more savvy governors can keep that type of rhetoric out of their pontifications, they may spark a discussion this country really needs to have.
Hypothetical for you, had this been a democratic governor a few years ago asserting his state's sovereignty, wonder what the press would have been? (yes, I know Fox's stance would have been quite different)
I really don't know. The concept of secession is so abstract and so very unAmerican that I really can't imagine ANY Governor getting any positive airtime on the subject.
Looking at the most liberal states, it would be considered ludicrous to even suggest such a thing. I would imagine that the folks on the right would use it as a very effective election tool during the next election cycle. This is a very dangerous precedence being laid out.
The event I witnessed yesterday told me a couple of things. First, the protesters could not, for the life of themselves stay focused. They complained against everything except the BCS Rankings and Bowls. Second, while an excellent format, I noted that, when confronted by questions [and no, I didn't mug anyone] no one was able to really move beyond regurgitating what they had heard or written on their sign. Also, we found it interesting that ALL of the group, when asked as a group would benefit from the Obama tax plan ["how many here make below $75,000 a year" was the question and every hand of every protester went up].
Once the local talk show host was distracted by an interview, the momentum dissipated quickly. A friend who was in Knoxville said the very same thing happened there.
