"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."
There it is, the oath that the eventual winner of this Presidential Election will say as he, or she, takes the reins of the most powerfull country in the world. In the context of today's procedings, and in light of all of the other well-defined reasons why the primary elections that HRC wishes to have counted would represent an unfair delegate grab on her part, let us just recall two salient facts. The states of Michigan and Florida were punished for violations of electoral rules of the Democratic party. They did so knowingly, whatever their hopes might have been regarding any actions taken in response. Also, the candidates ALL agreed that actions must be taken against these states for their actions, and supported the punishments at the time that they were imposed.
Now, if a candidate can't seem to be willing to live up to acting to preserve, protect, and defend the rulebook of his or her own party - but rather wants it circumvented for personal gain - ask yourself this question: How much faith do you have that they will preserve, protect and defend the Constitution?
