The day Obama signed the ACA, it became law. The two year long court battle only delayed its implement. And last Thursday, it is full steam ahead. Besides, the bunch of thugs really are not concerned about law abiding (Eric Holder, need I say more?).
All Republicans can and have said they will do, is after the election if Romney wins presidency and Republican control both houses. We can only HOPE this time GOP won't negate their promise, and my prediction is they will go wishy washy on us again.
Actually, I think the contraception mandate IS being fought in the courts as we write. Obamacare, in its entirety, is far from settled law. Other provisions will be contested as they arise. I think the individual mandate was only challenged first, because it seemed like a slam dunk. However, I agree with your point that the Roberts Court is left leaning. Kennedy, for example, is no sure vote for the right.
Actually, I don’t even like to consider it as right or left. It’s called obeying the clear intent of the constitution and upholding the rule of law versus warping the law to mean whatever one wants. In that case, the court definitely favors the barbarians.
