I mean, I'm not even sure which way I'd vote for climate. Here's one take: "Things are clearly out of control. We need climate mitigations that can be done unilaterally. One promising and surprisingly-feasible approach is a sun-synchronous solar-shade swarm.[1] That needs very cheap and frequent launches to be feasible. The only option is SpaceX/Starship. Politically, to get that going as soon as possible, it may be beneficial to have a weaker FAA. Hence probably Trump."

If you think the "business-as-usual" climate mitigations will be insufficient, it may be worthwhile to go for high-variance approaches that leave humanity better able to react relatively quickly to unexpectedly large warming.
