The problems are:
1) They are leaving a gap with Soyuz as the only operator. OK that Soyuz remains in the "taxi" mix, but they shouldn't be the only operator for years - for both pricing and national-security reasons.
2) Constellation isn't just a taxi service. It's a path for American human spaceflight beyond LEO for the first time since 72, back to the moon and beyond. As such it's a vehicle for national dreams, daring, leadership and pride. (in short, everything Obama is not)

THAT is the ultimate 'redistribution' - which well may have been his target goal all along.
And while everyone was/is watching and clamoring and demonstrating about the 24/7 health care "stealth care" bill watching his right hand, his left hand is doing the dirtiest work - it is, after all, the Islamic way.
