Potus will never miss an opportunity to add a little color to a truly historic occasion of this magnitude.
I would bet that this will draw out more traitors, the most vocal, to expose themselves.
The Fake Main Stream Media dish was completed long ago. Though no one cares much about it anymore, it is considered a Gag Dish, it has been included, and much like revenge, it is best served cold.
So let Potus give the other components time to catch up so that the feast will be ready all at the same time. We, the people, will enjoy it all the more when everyone realizes what both main parties are bringing to the table.
