Agree. Wood ran to expose McKissick as a never Trumper, IMO. Roots out SC good old boys club behind Graham. McKissick can't make a move now without Wood and Flynn on his ass.
Also think Graham had to ask Trump for a last minute endorsement, and that had strings attached, as well. Might be a need here, not sure, to dismantle SC GOP club to take out Haley, who I don't trust. Haley is never mentioned in the long face/long tooth clan, but her features could pass.
POTUS took the high road by endorsing McKissick, He's giving McKissick a chance to fuck up under national scrutiny, and McKissick will. Wood, who didn't need that job, he's better at other things, and Flynn can hammer away. Good cop/bad cop in play.
