As much as I enlarge this picture, I cannot determine who these campaign stickers represent. However, I cannot imagine that any Republican would put a drill through a tire, or otherwise vandalize a car over a campaign sticker. We might wish to do that, but we'd never actually carry out those thoughts. On the other hand, I've seen the opposite Party engage in that kind of vandalism all the time and have had it happen to me.
For those outside of Wisconsin, RAwhid Boys' Ranch is a charity operated by the Bart Starr Foudation that accepts donations of cars, boats, jewelry, furs, etc. which are refurmished and resold to support a ranch for boys in need of a home, discipline, and training. It's a really good agency.
