The dollar figure represents a significant haul for Mr. Squadron, who opened a citywide campaign account over the summer but only started raising money for it in late October.
According to the source, Mr. Squadron “is interested in running for public advocate, but is also looking at Brooklyn borough president and comptroller.”
The field for all three of those office remain relatively small, with only Brooklyn City Councilmember Letitia James and Reshma Saujani–an aide to current public advocate Bill de Blasio–thought to be looking at replacing Mr. de Blasio, should he run for mayor, as is expected.
If Mr. Squadron opts to run for borough president instead, he will likely find himself in a race with fellow State Senator Eric Adams, Assemblyman Nick Perry, and Carlo Scissura, a aide to current Brooklyn BP Marty Markowitz. Earlier this week, Mr. Scissura reported raising $126,000 for a possible run.
A former aide to Sen. Chuck Schumer Mr. Squadron took a somewhat unlikely path to the State Senate. In 2008, he defeated longtime Democratic State Senator Marty Connor in a fiercely contested primary one that saw Mayor Mike Bloomberg and Senator Schumer come out for Mr. Squadron while most of the Democratic leadership in Brooklyn and around the state came out for his opponent.
