How come liberals are so conservative with fuel and conservatives are so liberal with fuel?

All the people I know that drive a hybrid car are liberals or lean towards the left, all the people I know that drive trucks and Hummers are conservatives. Go to Whole Foods , watch the granola types as they park their Prius, you can easily tell that they are Liberals because of all their stickers on their cars. Now go in front of a gun shop, the stickers on the cars there will be more right wing oriented; the cars themselves will also have a much higher MPG. Maybe someone should come up with some new bumper stickers:

Liberals: fuel conservatives, Conservatives: fuel liberals

Now I called people driving a Prius and shopping at Whole Foods granolas. For some of you who do not know what I mean by that here is how Urban Dictionary defines granolas:

An adjective used to describe people who are environmentally aware (flower child, tree-hugger), open-minded, left-winged, socially aware and active, queer or queer-positive, anti-oppressive/discriminatory (racial, sexual, gender, class, age, etc.) with an organic and natural emphasis on living, who will usually refrain from consuming or using anything containing animals and animal by-products (for health and/or environmental reasons), as well as limit consumption of what he or she does consume, as granola people are usually concerned about wasting resources. Usually buy only fair-trade goods and refrain from buying from large corporations, as most exploit the environment as well as their workers, which goes against granola core values.

BTW this wasn't meant to offend anyone, I was just in a funny mood today. Must have been that Whole Foods 365 brand cola junk
