Good observation. What question the follows?

Is he unaware? ( Nescience)

Let's presume he is, what then does that tell you about him and his adherence to the rule of law?

What other reason could there be for someone like him to ignore the constitutional provision?

Does he share the same disability?

If not, what would then cause him to outright ignore the constitutional requitement? To combat a competitor for high office, would that not be a legitimate matter to point out? Or has politics become so divorced from the constitution that constitutional requirements no longer hold sway? If so, what does that tell you?
