As a PS to my last post, I should add that conservative wonks have long hated our system of employer-based insurance and wanted to get rid of it, and that any Republican "alternative" to Obamacare will almost certainly work to undermine it. The employer-based system of health insurance has long been crumbling. Obamacare, by offering an alternative, is accelerating the process. This will be resented, but not reversed. The question remains what will take its place.
