SpaceX is a young and aggressive company with clear drive and motivation to succeed.
Dive and motivation are necessary but not sufficient. Having those attributes doesn't mean they have a good product or the product with the best price/performance ratio. I have no idea of the relative merits of either company regarding this project but just because SpaceX is the new hotness doesn't mean anything. While I have no affiliation I've actually done some work at Boeing (many years ago) so I have at least a basic understanding of how that company works and what their culture is like. (FYI the part of Boeing I dealt with has a combative work culture I didn't enjoy at all) I'm confident they could offer a technologically competitive product. (economically competitive is less certain) Boeing has been sending up rockets for a long time so they are hardly new to the game.
While they might have been a risky bet because they were new, they would have backed their development record.
Boeing has a much much longer development record. Of course that might also work against Boeing but SpaceX does not have a long track record to go on. I'm as impressed with SpaceX as many others here but if they want to play with the big boys it isn't going to be easy and yes they are high(er) risk in certain ways. This means they need to be clearly better (economically and/or technologically) or they stand a good chance of losing to the "safe bet".
We need competition between these companies and giving SpaceX a chance to shine will make Boeing stop screwing over the U.S.
Umm, this IS the competition between these companies. This one bidding competition isn't the end-all-be-all regardless of which firm wins this contract. Plus you haven't exactly proven the assertion that Boeing is actually engaging in corrupt practices here. While I certainly wouldn't be shocked to hear that they were, that isn't anything close to proof. Absent evidence saying that SpaceX should get the contract because you suspect Boeing (without proof) of corruption is not a strong argument in favor of SpaceX.
