Four months ago The Nation and City Limits launched a blog to track Bill de Blasio's transition and his first 100 days in office—the sprinting start of an administration critically important to the progressive movement and to a city we love that has seen an alarming increase in social inequality.

In a wrap-up article in The Nation, I look at de Blasio's many successes so far—UPK, paid-sick leave, the legal settlements—and why his administration has struggled at times to get its message across. I also analyze the considerable challenges that now face de Blasio, from implementing UPK to delivering on a huge affordable housing promise.

Read my take on Bill de Blasio's “best of time, worst of times” first 100 days.
