Sometimes in politics you can lose by winning. I hope that isn’t the case here. In endorsing two DSA candidates — one in the 7th District and the other in the13th — in tomorrow’s primary, Mayor Mamdani has introduced tensions in the coalition that elected him. Unlike Bernie who is a longstanding Senator from a small state and secure in his position,

Mamdani is a new mayor of a city that is infinitely bigger, infinitely more diverse, and infinitely more complex. In these circumstances, the mayor’s success in moving his ambitious agenda forward tunns, I would argue, on his success in maintaining, growing, and mobilizing the heterogeneous coalition that elected him, especially the Black, Latino, and labor communities.

But in endorsing his DSA comrades, he runs the danger of creating divisions in this coalition, regardless of tomorrow’s results.Let’s hope that they are minimal and don’t come back to bite Mamdani and the larger movement whose unity and mobilization he will depend on going forward
