The grocery money is secure.
With all their high profile intervention, the administration cannot now allow GM to fail. If B.O. really doesn't want to be in the car business (like he claims), he'll have to make sure it becomes an attractive investment for somebody to take on. That's what I'll be watching for. And I agree that Ford is well positioned and should also do well - as long as they're not penalized for being self sufficient during this time of "great crisis".
USPS is still a quasi-govt agency, but with a mandate to be self sufficient (no tax dollars). It's not quite ready to really compete in an open market. That too is changing though.
