I would probably be a single-issue voter if a candidate for congress were likely to win and was aligned with me on this issue but opposed on virtually everything else.
One essentially-fantasy is to run for Congress directly. Unfortunately I haven't lived my entire life to my mid-30s in trying to become a viable political candidate, so this would be difficult. Central or Eastern WA is probably the best bet, along with starting a 50-500 person business which employs a lot of local people (manufacturing of some kind) and generally being an engaged local citizen for a decade or more. But that's a long term goal.
