the unexpected thing about Talking To Your Representatives is that it can actually work, if enough people are similarly mad about the same thing. you won’t get the elected on the phone. but they will hear about it from their annoyed staff, who might not have time to do anything else
Fun story: I was a senate intern during the Thomas hearings circa 91 and we did actually read all the letters, assigned them codes and they'd get a response. I opened a letter containing a large amount of pubes, (Thomas, coke can, pube) that fell all over my lap. Truly a wonderful experience.
