I believe this is an excellent time to articulate and circulate a petition to amend the US constitution to specifically limit the US Congress' ability to pass a coercive tax designed to force people to buy a product or service that an individual does not want. I cannot see how todays decision to uphold the Obamacare law is anything but an unmitigated disaster for liberty in America. This is a death knell for the concept of limited government in this country. A narrow window indeed exists for a movement to curb the unrestrained power of the Federal government. This unprecedented power will exploited to its fullest by the Congress unless dramatic action is taken, and taken soon.
