Easy......most SUV drivers are women and most women are liberal.
By the way, before I get flamed, I'm a woman SUV driver who loves the space for my kids.........I just know that most women are overly emotional and not logical when it comes to politics, I'm sorry to say.
Liberals don't hate all SUV's - they just hate your SUV. They also hate your air-conditioning, your cell phone, your gun, etc., etc., etc...
