My impression right now is that there is not a lot of difference in the two proposals in terms of US jobs. Engines and a lot of systems and avionics are already US-sourced. EADS will do more tin-bending outside the US, but has the upside potential of commercial freighters and export tankers, which Boeing doesn't offer.
So what we're really seeing is an internal fight between EADS states and Boeing states, wrapped up in the flag.
