I find the constitutional arguments against the PPACA risible. I am a bit superstitious in saying that but let's be honest here. This too is risible. The "mandate" was suggested in the 1990s. And, no other Commerce Clause challenge? Really? Meanwhile, on the tax issue.
[Update: Someone later provided details on the 1990s point but also loki13 in effect patted him on the head for being such an effective advocate. He might be but not really in a positive sense since his reasoning is specious. This isn't just a game.]
