It actually would be a blessing in disguise in that the issue of health care would at least no longer be a burden to Democrats -they no longer have to defend an unpopular law that even their base doesn't support. It would free up resources to go on the offensive and demand single-payer reform as the only long-term solution to our health care funding crisis. The base will be energized as never before, while Republicans (spin aside) will be deprived of a potent issue to use against the President.
I tend to agree here, and right-wingers who rail against judicial activism would be well-served to exercise caution here: there's a very dangerous possibility for them that if Obamacare is struck down from the bench, the democratic base will be rallied as never before, much like the right was with Abortion.
This. It will be the early 20th Century all over again with things like the Income Tax catapulting class issues to the same level of divisiveness that in recent decades has been occupied by "ethnic" issues, such as abortion.
