So look:
I don't like the ACA, and it makes insurance expensive and crappier, at least for me. The linked CNBC article says that it *looks* like the individual mandate will be excised from the law based on the comments during oral arguments.
So I'm not sure what more people were expecting. Once the individual mandate to purchase health insurance is scrapped regulating the healthcare and insurance markets is pretty obviously in the power of Congress under the commerce clause (as it exists in American law today. Don't @ me with crazy *expletive deleted*it). It's a bad law, but it's not unconstitutional.
So what did we really expect here?
