I don't know if it's still true, but pre-pandemic I used to have occasional contact with legislative types, and they regularly told me that physical letters carry more weight than phone calls, and email was a distant third.

Pretty much, the amount of effort you put into your communication is a reflection of how important the issue is, and how important it is to you.

Which kind of goes hand-in-hand with lobbyists. Companies don't pay them millions of dollars to send emails or rant on web forums.

Can confirm, worked as a Congressional intern.

Order of importance was (at least in 2011):

1. In person meeting 2. Physical letter 3. Phone call

Call the district office and see if you can get a meeting with the district manager to talk about the issue.

Then go to district events that your rep will be at, get the district manager to introduce you to the rep.

That's way better than calling the same phone line all the wackos call

Sitting out means those who do reach out have a louder voice with policymakers. You can't not participate and also be upset by the outcomes due to your lack of participation.
