Honestly, I would wait and see on this. Remember the progressive liberals didn't institute their changes over night nor will we return to some form of self government quickly. We need consistently win battles over years to win the war. Like I said it will all depend on how the GOP fights the definition of extreme in the future. Im just saying lets wait see, until then lets take the victory of several good judges put in position's to interpret law and not legislate it. You might be surprised at how many people actually like this type of compromise, granted they rarely have defining principles or distinct philosophies they follow, but they happen to be the coveted independents that are so important when it comes to election time.
But you don't win battles by not fighting. You may make strategic withdrawals, but not when you have the advantage (such as control of both Houses of Congress and the Presidency). It's also possible to win all the battles, and still lose the war. In this case by not fighting this battle, we may lose or at best hold the status quo on the Supreme Courts, which stinks. Once the Supreme Court takes a decision, it can take many generations to get it overturned. This was a very important battle, but one for which it's hard to get the general public very interested in, and one which is easily spun. As this case was.
