Well, I just got back and did a count.
Over the course of three days driving from Denver to Dallas, I saw twelve pro-Bush bumper stickers (Not including mine).
I saw one pro-Kerry.
Sorry, I forgot some other stuff:
When we stopped at a Denny's, people were staring at the stickers. Some smiled, some stormed away in disgust (After looking around and seeing me looking at them).
Unfortunately, there was a storm on the way home. I lost 4 of the 6 stickers due to big rigs blasting water on us.
