Contacting my representatives is about as effective as making a silent wish. Whenever I've done it, I'll either get no response, or a boilerplate reply which basically says "I'm doing this, go fuck yourself". Then I'll be added to their spam list. The truth is that my reps don't represent me and they're going to do what they want regardless. After all, I'm not the one backing the truck of money up to their front door.
