Well, the thing about the infamous CBO report is that, while I do concede that economics tip-toes between educated guess work and years of non-linear operations research studies, politically-driven economics are a dime a dozen (I am looking at you, Krugman) and unlike the popular claim the report doesn't actually prove that jobs were saved or created ("saved jobs" is not a term used by any economics major, a political activist, maybe, not an actual economist)

Jumping from that to Obama's relantionship with Congress, I'm sorry if I come off as mean, but Obama enjoyed his first two years in office pratically unopposed (full Democrat majority in the House and Senate), in which he pushed foward virtually all the major policies that we see in effect today and really his policies have changed very little since then.
As much as one might want to kick Republicans for not playing ball, part of the problem also lies in Barack Obama's let's say... narcassistic posture towards any kind of disagreement or any obstacle of sorts. And as far as blocking him in order to be a one term president, that seems hardly an hindrance, because in any functioning republic the opposition's role is to be just that: the opposition.
And to be blunt, Obama's challenges in office in this time period are akin to a mild discomfort compared to the amount of venomous ill will and Twitter-style murderous vitriol directed at George Bush.
I have nothing more to add to this topic.
