I hate the phone more than maybe anybody, but this is an anecdote I believe — from a congressional staffer:

Here are the important bits:

I worked for Congress for 6 years, and here’s what I learned about how they listen to constituents.

First, tweeting or writing on Facebook is largely ineffective. I never looked at those comments except to remove the harassing ones.

Second, writing a letter to the district office (state) is better than sending an email or writing a letter to DC.

But, phone calls! That was a thing that shook up our office from time. One time, a radio host gave out our district office phone # on air.

He was against our immigration policy and told our constituents to call. And they did. All. Day. Long. All I did all day was answer phones.

It was exhausting and you can bet my bosses heard about it. We had discussions because of that call to action.

If we started getting a pattern of calls, I called up our DC office and asked if they were getting the same calls and we talked.

Also...

1) Show up to town halls:

If you want to talk to your rep, show up at town hall meetings. Get a huge group that they can’t ignore. Pack that place and ask questions.

We held town halls consistently that fewer than 50 people showed up for. And it was always the same people. So, shake it up.

2) Be nice to staffers:

Are you noticing a pattern here? The staff are the ones who run the ground game for Congress. Work on helping them understand and learn.
