If a significant majority want change (isn't that how Obama got elected in the first place?)
A PORTION of those that elected Obama want the level of change you want. Many of them have other specific areas that caused them to vote for him. You conflate your goals with everyone else's. Since the majority of US citizens currently have healthcare, and they fear it getting worse, then they'd simply like to keep the status quo without too much change, since change is often for the worse for those who already have a piece of what is changing.
These are not the sheeple you are looking for.
