For this study, the data…

A nice article in Zerohedge about the recent rate hike for Tesla owners (link). Of course, Tesla is crying foul.

When Hillary Clinton unexpectedly lost the election in November 2016, it was high time for pundits to espouse their pet theories for the shocking losses suffered by the Democrats at all levels of government. The usual suspects were put on parade, such as “Bernie Bros” who abstained from voting and the “deplorables” who voted against their own interests. For the first time, two unlikely entities faced scrutiny: the social-media giant,…
