Party ideologies are OK, but don't be mislead by them. Of course, there are different approaches to governing democratically. Nevertheless, Party-ideology fixates one approach and does not deviate from it.If an ideologue deviates from the dictates of his/er Party, he/she is considered a turncoat. Of course, there are subtle differences within this deviation. Example, The decision approving Obamacare appears as a deviation from Party principles but, the dictum in the decision weakens several Constitutional approaches to federal soveriegnty. Future decisions can now use it to cause lots of damage to the people at the bottom. So, one Party subtly lays ground-work for future Constitutional connections that furthur weakens the bottom of government,viz. democracy. Remember, the Constitution crafts a triadic form of government; not a dualistic form. The problematic of a dualistic Party system is that ideologues hang on to their beliefs as if gospel-truth. Any Party loyalty in a dichotomous set-up, will just go from one side to the other and vice-versa; there are no alternatives. Thats why government must be perceived as a triadic form that is always in motion and seeks only to harmonise the whole triad. When government has a dichotomous party-system, it automatically endangers democracy. Why? Because a democracy is "of the people", "by the people" and "for the people". Once polititians divide themselves into a dualistic system, they can no longer relate to the third aspect of government, which is the most important and the fundamental part of a democracy, viz. the bottom. Of course, a Two-Party system can function properly if it adheres to the Constitution. But, that requires an honest and sincere flexibility between ideologies and not insiduous groundwork for future party-ideologies. The reason any Party-system can function properly, if it really wants too, is that the Constitution crafts a triadic form of government; not a dualistic form. The only requirement is adherence to the Constitution. Of course, this furthur requires an impartial Judiciary; and where are we going to find that? The Judiciary is a very important aspect of government because it defines the lines of a democracy. The Judicial branch must stop playing politics. Regardless their ideologies, they must be impartial in order to be Constitutional. If they can't be impartial, what good are their marble halls?
