Some members of the Idaho legislature (and in other states as well) are talking about bills to "nullify" Obamacare. As much as my sympathies are with them on this, this is not going to fly. There are legitimate criticisms of the constitutionality of parts of Obamacare, and legitimate criticisms of the sensibility of other parts of it, but the notion that states get to ignore federal laws that they don't like just because they don't like them is not going to fly.
The lawsuits challenging the constitutionality of parts of Obamacare are the way to go on this. There are parts of this steaming pile that are likely to be constitutional. Not everything stupid, corrupt, and foolish is unconstitutional. At some point, we have to actually get the people to show up to the polls in enough numbers to change the composition of the Congress and the White House. In a society as depraved and corrupt as America, good luck! We need to start working a bit harder on persuading the masses that right and wrong still mean something.
