The kind of conversation you have with your state legislator will vary a lot by how much the two of you agree on the issues you are bringing up. FCNL provides some advice for approaching the differences on these pages:
My representatives are great; now what?
My representatives never agree with me; now what?
We particularly recommend that you look at FCNL’s advice on intermediate places where you might be able to move your representatives, even when they do not move all the way to where you want them to be.
