Obama shows takes a stand, showing some serious spine

[Sbane]

I think Obama's genuinely frustrated at his party's ideological base. He thinks he's doing the practical, pragmatic thing from a policy standpoint and that they should therefore all get behind it. What he doesn't seem to get is how the politics plays out and that he's putting himself at serious risk of a primary, which would be very bad news if he wants to run for re-election.

Who would challenge him? Hillary is the only viable candidate. And that wouldn't be a challenge from the left, would it?
