Why is that such an aberration? I don't own a Pious, er Prius but I've driven one and I liked them. I'd be tempted to buy one some day, and I ain't no commonist, ya know what I mean?
My roomate had a Prius for a while; I like the car personally. I think it’s just the connotation that a Prius owner would be a rabid environmental wacko thus being a Democrat. Our local DJ jokes the same thing (Prius with Trump bumper sticker).
