President Trump isn't remotely concerned about alienating some millionaire professional sports players (or NFL commisione). His real audience is the same one responsible for his victory in November of last year. Looking forward to the battles ahead on tax cuts for the wealthy, restricting immigration and, not the least, his reelection in 2020, Mr. Trump wants to keep the fires stoked among the true believers. After all, it's the squeaky wheel that gets the grease.
