- Julian Castro (foreground) makes a point while his brother Joaquin looks on.
Former San Antonio mayor Julián Castro, now chasing the Democratic presidential nomination, and Democratic U.S. Rep. Joaquin Castro will make their official endorsement at a Saturday rally, according to a press release circulated by Nirenberg's campaign.
Nirenberg, a single-term mayor with a largely progressive agenda, faced an unexpectedly tight May 4 election against Greg Brockhouse, a one-term councilman running a populist campaign. Neither reached the majority needed to close out the contest.
The potential gain from the Castros' endorsement is that the brothers wield considerable clout on the West Side, where Nirenberg was unable to turn out enough voters to counterbalance Brockhouse's strong showing in the Northern suburbs.
The candidates face off again in a June 8 runoff.
