I'm a one issue voter.

If a candidate doesn't prioritize laws which prioritize a transition to sustainable economies/ecologies, really there's not much else to say. The basis of civilization - implicit rights to air, food, water, shelter and the ground truth of non-human life that underlies any other rules and customs and narratives - is eroding under human overpopulation, uncontrollable wildfires and storms, melting ices and escaping methane, moving growth zones and migration patterns.
Climate change is not a straw man.

Furthermore, this need not be solely implemented with laws and incentives: it also needs leadership that lives this attitude. The bully pulpit is powerful.
