Look here: The Twitter feed of Rupert Murdoch — executive chairman of 21st Century Fox, the parent company of Fox News — envisions a bright future with a unified Republican Party behind racist-bigot-sexist Donald Trump. This line of thinking puts Murdoch in good company with colleagues who celebrate Trump’s brilliance as a strategist and orchestrate applause for his most extreme ideas. It might also serve as an insurance policy against Trump pulling out of Thursday’s Fox News debate — moderated by Trump nemesis Megyn Kelly, along with Bret Baier and Chris Wallace. Whatever the hazy motivations behind the mogul’s tweets, boosterish commentary of this sort will merely make it harder for him to recover once Trump says or does something really offensive. And by really offensive, we’re talking about something worse than the many very, very offensive things he’s said since June.
