From the Mercatus Center:

New York is by far the least free state in the Union.

From Jane Mayer’s piece on the Kochs and PBS:

Among the wealthiest residents of 740 Park is David Koch, the billionaire industrialist, who, with his brother Charles, owns Koch Industries, a huge energy-and-chemical conglomerate. The Koch brothers are known for their strongly conservative politics and for their efforts to finance a network of advocacy groups whose goal is to move the country to the right. David Koch is a major philanthropist, contributing to cultural and medical institutions that include Lincoln Center and New York-Presbyterian Hospital.

Snarky conclusion: if the Kochs love freedom so much why don’t they move to the Dakotas?
