California's Proposition 87: Tax California Oil to Reduce Consumption of Foreign Oil
If you go the web site of the yes-campaign how their most important argument for raising the tax on oil extraction in California is to have "less foreign oil" and increase "energy independence". That's right: the idea is to discourage oil extraction in California so as to induce Californian's to use less foreign oil. Normal people would realize that if there is less California oil, then the result will be that people in California will demand more foreign oil as a substitute and certainly not less, but these people apparently don't mind embarrasing themselves by campaigning using the absurd assumption that less California oil will mean less foreign oil.
But perhaps they think this tax will raise oil prices and so lower overall consumption? No, on their web page they also come up with another absurd claim, that this will cost consumers nothing, which rule out the idea that this is the mechanism they imagine.
So what they believe is that if you reduce the supply of something by taxing it, it will not lead to a higher price and it will at the same time lead to a lower supply of untaxed foreign substitutes.
These people just must be competing for the "stupidest people alive" award. What else could motivate people to embarrass themselves with such stupid reasoning is beyond me.
