You're tripping over your own argument. Exceptions should not be used to argue for the rule but you turn your own argument on its head by arguing this as a special case where the Congress should not be involved. In simple point of fact, genius, the Congress has the Constitutional prerogative to involve itself as it sees fit, and that is the actual general rule. And that by the failure of the SCOTUS to limit in other cases where the opportunity to define Congressional limits as set by the Constitution have created bad precedent (mal stare decesis)
Nice try though, nice exposure for you ...
I am sorry but when I read the Constitution, I do not see where it is granted the power to go into Special Session for the sole purpose of involving itself in personal matters of a private family.
It does not sound like something that a Small Government Conservative would advocate.
But there seems to be very few of us Small Government Conservatives around these days.
