Utilizing the GoToQuiz.com database once again, the percentages of self-selected participants who politically identify as Libertarians, by state:
|6) New Hampshire||7.2|
|11) South Carolina||6.7|
|22) North Carolina||6.2|
|27) New Mexico||5.8|
|35) North Dakota||5.5|
|36) Rhode Island||5.5|
|37) New Jersey||5.4|
|41) West Virginia||5.3|
|46) South Dakota||5.1|
|47) New York||4.9|
|51) District of Columbia||2.9|
The Mises Institute, at the eastern end of Alabama near the Georgia border, looks to be the American epicenter. More generally, the South is the region of the country where identification is strongest. I find this a little surprising given the heavy military presence in the region, the relatively low percentage of non-Hispanic whites in southern states, and the general impression that big-L Libertarianism is increasingly becoming low-tax progressivism, more Bill Weld and less Hans Hermann Hoppe.
On the other hand, Libertarianism is the only political philosophy that treats the idea of political dissolution seriously, something that has had a historically strong appeal in the South from the mid-19th century onward.
Note that the database shows 6.8% of Americans identifying as Libertarian at the national level. That’s about double the amount of support the party gets in actual presidential elections. Some of this discrepancy is due to the poll’s self-selection bias–white men are more likely than other groups to take surveys like this and also more likely than other groups to be Libertarian–and some of it is probably due to “this election being the most important election EVER so I must go for the lesser of two evils and vote for [Republican]/[Democrat] this time!”
