I think the lack of correlation between public opinion and government policy is more than satisfactory to demonstrate how much our federal legislators care about your phone calls, yes.
I hear you and acknowledge it is frustrating. But your assumption seems to be that your view is shared by all and thus “public opinion” aligns perfectly with what you believe or at least that a majority agrees with you. We all do this because we imagine our opinions to be sensible and hey, why wouldn’t other people share them? But they don’t.
