I'm sure that Tesla (or some "individual" or "501" non-profit front group) donates HEAVILY to Democrats, and they get the taxpayer funds funneled to them to subsidize their un-economic, un-wanted, non-competitive product.
Subsidies to "green projects" and "alternative energy" ALWAYS are un-economic, un-reliable, un-wanted, etc., but can only fill the pockets of major donors via MANDATED/FORCED taxpayer funds that are sent to them (sorta along the lines of Obama Motors, etc.)
