The 85% number you throw out there is far from fact. It's also not health care that is provide by insurance companies. It's health coverage. Health care is between you and your health provider.
Regardless of weather or not someone has "coverage" the number of medical related bankruptcies in the last few years prove the insurance companies aren't living up to their end of the policies and/or a huge number of people who have "coverage" are significantly under-covered. So the only thing we do know for sure, is that the status quo is not working for American people as a whole. Although the blame for skyrocketing healthcare costs needs to be shared by doctors, patients, hospitals, pharmaceuticals, etc... the overwhelming amount of blame falls to the insurance companies.
As far as your last statement about this being all about Obama... I can just as easily contend that it's all about the Republican desire to knock Obama down. Statements to the like have been well documented from the right for the last year. The lack of any real ideas from the Republicans about how to address the issue of healthcare, aside from "leave it the way it is", is just icing on the cake.
I would be fine starting over. But is there any indication the second time would be any better than the first. If your original post is an indicator of the attitudes that the right would be bringing to the table, then starting over is absolutely pointless.
