Why is it that Bloomberg has run an article so light on the details of the financial ownership of these companies by private equity firms (something they should be quite expert in), and instead mostly consisting of old news stories about how close some past elections have been (not their area of expertise and barely relevant if the idea is that the entire voting system can be wholesale rigged)? My guess is that it's because if you dig into the details, there is little actual control being exercised by those PE firms, making this a non story.
