I read it as a romanticized version of Adams taking a bet on Trump early on. Numerous of his bets have turned wrong, but overall his odds are fairly honorable I would say. Now he can get the good role in saying he "predicted" Trump victory. No. He just placed a bet. Numerous fringe political analysts also betted on Trump at the same time, we just don't hear about them because they are less known than Adams.

My belief is Adams listened to these fringe analysts' arguments and they convinced him enough so that he went public with the idea, adding some of his own genuine take in the process (the "persuasion" thing).

Among his failures, he recently "guaranteed" in early 2020 that the Dems presidential candidate would be a woman. Interestingly enough, nowadays he doesn't talk as much about this losing bet.
