Even as a Trump skeptic I can see there is nothing “there.” It’s all smoke and mirrors, without the smoke and mirrors. The only thing that is keeping this alive is Trump’s juvenile behavior, but to act demure and simply say, “There is nothing there. Case closed. No further comment,” is beyond him. But he has no impulse control and his Gotham Grifter ego demands that he make himself the enter of attention, which might eventually bite him in the nether regions. Just shut up already, Mr. President, and pretend to be presidential.
My only problem with your analysis is that it’s the traditional Republican office holder approach, and the last one to fall victim to it was Dubya.
Rising above it is the typical GOP Inc playbook, and it never really works.
