Here are the states that voted for Romney at over 60%, therefore can be reasonably assumed to be most likely to support secession.
Utah - 73%
Wyoming - 69%
Oklahoma - 67%
Idaho - 65%
West Virginia - 62%
Alabama - 61%
Arkansas - 61%
Kentucky - 61%
As you can see, only three managed to get over 2/3 against Obama, as I said in my earlier post.
By contrast, in the 1860 elections NINE states registered not one popular vote for Lincoln.
Now that’s a regional division.
I am ignoring here the fact that a LARGE percentage of 2012 Romney voters would not support secession.
Romney as a metric? That’s pretty funny!
Your ‘regions’ are states; my map showed much smaller ones: counties.
The high population centers overwhelmed the more sparcely settled rural ones when the votes were totaled for the states.
