Call your house representatives, have them legislate on and forbid this practice, be explicit about not voting for them if they don't make it part of their platform.
My general assemblyman has run unopposed since I've been old enough to vote; my congressman's district is so jerrymandered he's got better job security than a licensed plumber.
Then volunteer to phone bank for someone in a swing state where a vote may make the difference, and write other representatives. It's not illegal to tell other reps that you feel under-represented and the issues you are concerned about
Dude I'm from a Red State, we don't have a government of, for and by the people here. Writing my congressman has less of an effect on society than pissing in my own mouth.
What I'm actually doing about it is not eating at my local Wendy's ever again.
