This could be one of the most important rulings in history. It will define whether or not the country is actually run by the Constitution or not, as it can clearly be read.

If it goes the wrong way (as I, and anyone else with a halfway decent grasp of English, reads it), it could set the stage for a future MAJOR shift in government. That, on top of the MASSIVELY unpopular NSA surveillance of Americans, would be a clear indicator of a runaway fascist state that the majority of Americans would absolutely not support. This sets the stage for a confrontation between those in power, seeking to maintain it, versus those who no longer willingly give them that power.

I also don't buy that "whatever the Supreme Court decides is correct and just and lawful", otherwise you would not get these split decisions. It is clearly a political body, and this ruling is going to tell us quite a bit about who is pulling the strings.
