"Seeing the light" is a relative term. This is the same column in which he still tries to make an intellectual case for Reaganomics. It's not as if race baiting and denialism and witch hunts are new to the GOP. Brooks wants to go back to the "good old days". I wonder how far back? Stonewall? Jim Crow? Red scare? Slavery? The good old days were shit and his party has been trying to get back there for a long time. He isn't seeing any light. He's seeing his own shitty reflection laid bare in the rhetoric of Trump et al.
