wrote that 22 states permit direct sales of automobiles by Tesla to retail buyers, and of those the majority--14 of them-- voted for President Obama
There is a much fresher data-point for the political leanings of those states — we had elections a month ago. That this non-biased and bi-partisan article — the kind we've come to expect from the Newspaper of Record — chose to use the two year old data instead to illustrate its point, means, the point probably is not supported by the more recent poll...
He suggested that Democratic California, Illinois, and New York "have freer markets in auto retailing than Texas," which is presently Republican.
Is it "freer markets" for everyone, or just for the "green" technology — which got a major government loan (on very sweet terms) to survive and ought to be helped to avoid embarrassing the Democratic administration? Would those Democratic bastions of free markets be as supporting of freedom, if it were about sale of, say, high-capacity toilets?
If you really care for free markets, you'll vote Libertarian — with anybody else you still need a bloody permit to do (or sell) almost anything. Splitting hairs about who is more likely to permit this vs. that is stupid — you have your right to pursue happiness. Selling cars the way you want certainly ought to be covered by that.
Is the small bit of evidence enough to make a case?
No, it is not. To show, which party supports freer markets, one would need to study the market-freedom across different goods and services. Cherry-picking one item, that is so dear to one party's heart, in an industry, that is heavily-regulated by all states (as well as Federal government) is meaningless and reveals nothing but bare partisanship.
