What in the world gives you that impression? The PPACA, like just about everything else the President has proposed, passed along purely partisan lines.
Now, we can assume that the same Republicans who have been pushing for a default on America's loans (you know, basic stuff that everybody knows better than to do) might, somehow, have started acting reasonable if the President was just a little more "forceful."
...Or we can avoid such assumptions because, in my not-so-humble-opinion, they're completely contradicted by the reality of the political circus in Washington today.
For instance, we can't get our Representatives to agree to pay the bills for the spending which they've already authorized--again, just about the most basic thing in the world--but we can get our Representatives to agree that chimpanzees should be able to retire in style.
I don't honestly see how any man or woman can be expected to perform well under such ludicrous circumstances.
If that was the case, then he'd have avoided the PPACA and the ARRA and TARP and, you know, all the things that he's been vilified for over the last 5 years.
