You are focused on the mechanics of how it got passed. But it was clearly his major priority and wouldn't have happened without him being in office. So, I apologize, but your statement seems at best completely inaccurate to me
Its obviously not demonstrable, but perhaps not; while the attacks that were thrown at the effort Clinton spearheaded as First Lady were largely unjustified, and since the style of plan both Clinton and Obama supported (of which the ACA is an instantiation) isn't much like the effort Clinton spearheaded (and is, in fact, more like what a number of insurers proposed in response to that), there were a lot of political negative associations with Clinton and healthcare that Obama didn't have.
> Personally, I think it would have sailed through much more easily had she been in office.
Based on...what, exactly?
