I don’t know anything about this McKissick (will look into him some other time), but POTUS also endorsed Governor Kemp and several others who proceeded to stab him in the back. Where endorsements are concerned, I’m guessing that at least some of them were to set up bad characters for their eventual exposure. I have no idea about the nature of the DM vs LW endorsement for that particular office.

Furthermore, irrespective of endorsements or lack thereof, the fact that Attorney Wood just called out corrupt officials for claiming his voter eligibility in the state was fraudulent, putting them on notice - what this particular article is referencing - would seem, at least to me, to be a positive.
