It's simply not credible for a president to threaten that "if, from this point on, Republicans think they can ... [fill in the blank] ... then they've got another thing coming"--as that president is capitulating at this point.
Obama's political office has lost touch. That news conference wasn't just a bad idea. It was an embarrassingly bad idea. The president pre-conceded what two months ago were unthinkable concessions, and remain utterly unnecessary ones. Now, notwithstanding Congress's actions on the Senate "deal," Obama is permanently lathered in its malodorous worst.
The administration seems discombobulated. I know the president and his people are tired, the campaign was a long one, and the issues confronting them are daunting. But this--today, and recent days--is perhaps the most maladroit launch to a second term in presidential history. It's so bad, it's embarrassing.
