The Congress got to DC with support from about half of their respective states and districts. Trump takes with him the support of about half of the country. He knows it and they know it.
His message will be put as he deems fit, but I imagine it will go a little bit like this: "We are the GOP. Existence, as you know it, is over. We will add whatever in your biological and technological distinctiveness is worth saving to our own. Resistance is futile. Assimilate or die." There should be no more failures to communicate, fancy footwork or disrespect from these courtesans after today.
