It was probably inevitable that Alfred Johnson would end up in politics: His mom and dad — philanthropist Maxine Isaacs and former Fannie Mae and Kennedy Center chair Jim Johnson — met while working on Walter Mondale’s 1984 presidential campaign and are still big players in the Democratic party. Now Alfred, 24, has scored a primo White House job as special assistant to Bill Daley, the president’s new chief of staff. The Sidwell Friends alum graduated from Stanford in 2008 with a degree in political science, worked on Obama’s presidential campaign in New Mexico, and spent the last two years at the treasury department. When Daley was tapped in January to succeed Rahm Emanuel, he asked Alfred to join him in the West Wing. No details on the new gig, but his desk isn’t far from the Oval Office.
