At the risk of being called a "Tenther" by folks who give no indication whatsoever of having read The Federalist Papers and The Anti-Federalist Papers and possibly not even the Constitution itself, I must note that Henry Hudson's ruling that Obamacare's "individual mandate" is unconstitutional is something of a no-brainer for anyone who's actually read those documents.
I'm very serious. The issues involved are not complex, not hard to understand at all. You might want to start with, say, Federalist 41.
Anyone who tells you Obamacare is constitutional is either ignorant as, ah, aitch-ee-double-toothpicks or lyin' through their insertyourexpletiveofchoicehere teeth. Or possibly just dumber than a bag of hammers.
