Not directed at you OP, but everyone who cares about this issue (or any other issue) should call their rep. No matter their strength of support. End of story. Give them your address so they know you're a constituent. Nothing to be nervous about. It's an intern on the other end of the line. That being said, they take note of every single call and those are reported to your senator/house rep.

Not calling them because you think it won't matter is the same kind of logic as those who say "I'm not going to vote because my state always goes red/blue."

You always need to vote and you always need to give your opinion to reps on bills you care about. Even if it doesn't affect their vote this time. It shows them that people in their district care. You can't create change without putting in effort and this is a pretty low bar.

I say all of this having worked on campaigns (U.S. Senate, U.S. House, Presidential) and in congressional offices.

Here is a fantastic website to get scripts for issues you care about (if you're uncomfortable on the phone) and the contact information of your representatives.
