Not exactly cheating

This isn't cheating. It may not be nice, but its hardly the same thing as accepting registrations for the other party and then throwing them in the trash. There's nothing wrong with either party trying to only register their own voters. In fact, the canvassers were politely saying "thank you" and walking away. That certainly doesn't leave anyone with the impression that they were registering, when in fact they were not. Anyway, why should the GOP pay to sign up Kerry voters? Answer: they shouldn't.
