Imagine if Obama or Hillary said they did not swear an oath to support the constitution....... red-necks would have a meltdown.
? “I (Name) 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.” ?
But Trump knows all the best words, and "support" is not in there. As the guest commented, "too smart by half."
