Lots of interesting behind the scenes info on the campaign. For example, apparently things got a bit messy with Brad Lander:

Mamdani’s relationship with Brad Lander, the city comptroller who in the final weeks of the Democratic primary essentially turned his own mayoral campaign into another leg of Mamdani support, is still recovering from a rocky patch over the summer, according to four people familiar with the matter.

Lander told a variety of leaders that he was interested in a top position like first deputy mayor in the administration, in what a range of anxious New York leaders saw as an implicit promise that an experienced hand would help professionalize Mamdani’s City Hall. That did not go over well when word got back to Mamdani’s orbit.

After nearly a month when they did not speak, by Labor Day, Lander was telling people maybe he would not be joining the administration after all.

The two have talked through this recently, and while no job offer was made, Lander has renewed his help for Mamdani in the campaign.
