The real issue here is two-fold; nobody cares about this particularly ("laws only apply to other people, not me!"), and that voters tend to act against their own self-interest (remember "joe the plumber"? too poor to have health insurance, but didn't want the government to give it to him for free? what!?)
Personally, I'm working on technical solutions to ensure that people "infringing on copyright" can't be prosecuted. (Or rather, so that their network providers and their own machines can't provide evidence against them.)
Things like IPredator are a good start. I can almost guarantee that if you use that service for Bittorrent, you won't be going to jail for your file sharing. Tor is even better (but very very slow). I hate technical solutions to legal problems, but right now, they work very well. That's why nobody really cares about this; people will pay their $10/month for an untraceable account in some country that hates the US (there are plenty), and they will continue to "steal" TV shows and movies. (Until the movie industry starts pricing movies correctly, of course. Make non-DRM'd new-releases a 99 cent download, and piracy will be gone overnight.)
