The current administration has bloody well succeeded by waiting for commercial manned spaceflight to fill the role. And trust me, the Shuttle needed to die. It was a politically compromised design which led to it being expensive and unsafe. And if the current administration didnt sit on their hands, any crew carrying rocket they made would probably squeeze the likes of spacex out of contention. Not on price or efficiency mind you, but on government mandated usage by NASA. Much like the shuttle did for 30 years.
