so, given the choice?

?
Wasn't the Constitution written for the people, by the people? Just when did the people decide some branch of the government got to interpret it anyway?
not exactly. it was written to define the limited role of government and to clearly give all other rights to the states. because we are not a democracy, "the people" didn't really have to many defined rights. the bill of rights was added to identify certain individual rights, and state that all other rights are given to the citizenry and the states.
the people were sheeple.

there are two thoughts on interpretation of the constitution by the courts. some of us believe that rulings should be made according to a strict interpretation of the constitution. in other words; what did the writers of the constitution actually intend and why. this is often done by taking into account other writings of the founders. there is a danger in this. the so called "separation of church and state" ruling was brought about by a casual reading of TJ's response to a question by the Danbury Baptists. the response was not taken in context with the question.
the other line of thought is that courts should interpret the constitution according the what the founders might have thought in a modern world. the "living document" line of thought. this gives the courts the green light to do pretty much what they want, because you can mentally develop a historical character any way you wish. someone who wrote against slavery can be brought forward to support abortion. isn't being forced to have a child you don't want, a kind of slavery?
anyway, that's a gross over simplification, but you get the idea.
this election, for me, is more about the supreme court, than about presidents. presidents come and go, but supreme court justices are forever! of course, once we are fully in bed with the UN, it will be difficult to extricate ourselves from that mess........
