Is this strike two for President Trump? That seems like the subtext of the ruling at home plate by America’s constitutional umpire, Chief Justice Roberts, after the president’s demand to impeach an unfriendly federal judge. That’s “not an appropriate response,” the chief justice says in a rare public statement. It follows the rebuke of Mr. Trump in 2018 by the chief justice, who averred then that there were no such things as “Obama judges or Trump judges.”
