Yet if there is a renewal wing in the Democratic Party, Mr. Emanuel is its sole inhabitant. He calls for education reform, a social media ban for kids under 16, and even a mandatory retirement age of 75 for federal officials. (If adopted and applied to the presidency, the 66-year-old Mr. Emanuel could serve only one term.) Rather than echo activist demands to abolish Immigration and Customs Enforcement, he wants to “end ICE as you know it and you see it today.” Asked if a man can become a woman, Mr. Emanuel said no. Cue the online outrage.
