I don't see how this has anything to do with politics, since SpaceX is a private company. Also, it's not SpaceX's first launch. It may be the first launch of the Falcon 9 rocket, but there have been others that SpaceX has undoubtedly learned a lot from.
Obama unveiled a plan in February to end the Orion spacecraft program and use private companies to launch US assets into orbit, for which he received copious amounts of criticism, from all sides. (He announced a scaled-back version in April that still relies primarily on private companies to provide transit to space.) That's what the parent is referring to — it's not just blind politicization of an irrelevant topic.
According to the other comments (and SpaceX[1]), SpaceX has a contract with the government to deliver cargo to the ISS when the shuttle retires. It has plenty to do with politics.
