There’s no mention of space policy in the Democrat Party platform. It mentions Apollo, but only as an example of how the nation can accomplish great (non-space-related) things when it sets its mind to it. As I noted in a comment there, it’s the old “if we can send a man to the moon, why can’t we solve world hunger?” platitudes.
No shock–there’s been no visionary space initiative on the part of any Democrat president since Kennedy (and I’d argue that even Kennedy’s wasn’t that visionary, since the vision was mainly to beat the Russians to the moon).
I would expect to see the president’s new vision in the Republican Party platform. It would be a monumental screwup, and indicative of its true priority, if it’s not.
