I wouldn’t consider your questions applicable since the constitution is all but being trashed now, and long before the supreme court would have anything in their hands in which to rule on. Obama makes his own rules which never are considered according to our constitution...only in how he can manuver around it if it becomes necessary.
The country is moving fast into a socialist country and therefore our constitution will be nothing more than a document if things continue...and currently being pushed as absolete.
I’m not sure what you’re getting at. Are you saying that since Obama is trashing the constitution anyway, you would be fine if he were to ignore a supreme court ruling declaring obamacare unconstitutional. Or are you saying, he may not explicitely and formally ignore it but will do so surreptitiously, so we’re pretty much at a dictatorship regardless of what happens.
