ELI5:What impact does calling state representatives have?
gpt
Individually?  Not a great deal.  One voice isn't much when a representative is working with hundreds of thousands.

But a bunch of them?  You'll get a response at minimum.  To paraphrase Wayne Wheeler (the guy who got Prohibition passed) "the primary desire of any American politician is to get and keep a job."  If you make it clear that they need to play ball with you to get/keep their job... they'll work with you.
