Re: #1, both of my senators' numbers terminate in a recording that asks me to leave a message with my contact information. I have a hard time believing anybody listens to these. Am I wrong? More broadly, I talked to one person at the office of one my state's reps. I complained about this order and said I hoped the rep would voice his opposition, and the person said the rep would. But how much does that matter, especially since the rep is in a heavily Democrat district already? Is targeting swing Republicans a better idea?
