This is one of the many places where the rubber hits the legal road with PPACA...and possibly drives into the legal ditch.

"On the issue of the so-called "individual mandate," the law's provision that all Americans obtain healthcare insurance, Vinson said the plaintiffs had "most definitely stated a plausible claim" for their objections.
"The power that the individual mandate seeks to harness is simply without prior precedent," he said."
Yes, Vinson is a Reagan appointee, so let's go ahead and get that on the table now. However, I think this is one of the most significant constitutional issues with PPACA: the potential misuse of the commerce clause by the Feds. Its also critical because the individual mandate is the glue that holds the "economics" of the PPACA together.
