Disobedience to any federal law is frowned upon in the courts, especially the federal ones. Just wait for a judge to put someone in jail for not having Health Insurance and the precedent is set.
It may come about because a man didn't buy insurance for his wife and kids. Maybe even because he could not afford it. But a judge could declare that to be spousal and child abuse; throwing him into jail. From there it could be interpreted broadly.
Welcome to the Brave New World.
But again, Barack Obama oughtn’t to have any say about this.
