"Want to get to Mars? Well, NASA needs money to do it, and the president, along with Congress, mostly calls the shots. But NASA has been consistently underfunded over the last decade, and only saw its budget restored to healthier levels in 2016, when Congress carved out $19.3 billion for the agency. With missions to Mars and Jupiter on the horizon, and ambitions of curbing US dependency on Russian launches to the ISS, NASA's no doubt hoping that the next president keeps the money flowing."
Keith's note: Space is just a blip on the political radar. Rarely, if ever, has it had any influence on a presidential election whatsoever - and then, it was fleeting and usually on late night comedy shows. Nor is it likely to change during this election. Besides, whatever you hear during the campaign will be revised and reinterpreted after the election. The candidates forget the issue 2 minutes after they answer a question about it.
Nothing on the horizon suggests that there will be a large increase in NASA's budget. Nor is anyone really targeting NASA for drastic cuts. Given the large commitments the agency is already in the middle of, and the prospect of flat budgets, it is unlikely that there will be any seismic shifts. As for the #JourneyToMars - absent a large infusion of money (again, not likely) the current pay-as-you-go, we-don't-need-a-plan approach is simply not going to get us to Mars any sooner.
The most that space advocates should hope for after the dust settles is that the agency will be held more accountable for its performance and that some budgetary and policy stability will be injected into things already underway so as to make them progress more efficiently.
