Given his resolute stance against such policies, I do not think he can bring himself to fake it, not that he ever did at any time that I can see.
McConnell will “feign” support for MAGA if it is necessary to survival of his position.
McConnell is holder of the purse strings for Senate campaigns. The donors of the funds for that purse are the true bosses of McConnell. But if MAGA permeates the Halls, McConnell will confer with his masters to carve out a new line of doublespeak to position himself over the “temporary” MAGA wave.
We’ll know we are winning when and if McConnell steps down and out, and Kentucky gives us a trustworthy candidate to replace him.
