Roy Moore's victory in the Alabama Republican run-off has been represented as a big loss for President Donald Trump and the Republican establishment, but that's not really true. While the president did campaign on behalf of Luther Strange, the former Alabama attorney general appointed to fill Jeff Session's seat when he became U.S. Attorney General, Mr. Moore appears as dedicated to the president's worldview as anyone. In many ways, Mr. Moore is more Trumpian (nationalist, populist, unethical and happily offensive) than Mr. Strange ever was. He even won the endorsement of Stephen Bannon, the president's former chief strategist.
