A former Brooklyn councilman, de Blasio is one of two likely Democratic contenders with deep ties to the borough.

If the last two elections are any guide, in 2013 just under 30 percent of the votes in the New York City mayoral race will come from Brooklyn—more than from any other borough. With two native sons (Public Advocate Bill de Blasio and former Comptroller and 2009 Democratic nominee William Thompson) in the mix, Brooklyn will be an interesting electorate to watch.

So far, of course, there’s not much to see. But that doesn’t mean the race isn’t taking shape behind the scenes, and in the campaigns’ bank accounts. While the election is nearly two years off, some $20 million has already been collected and more than $3 million spent by municipal candidates.

The six likely mayoral candidates—media executive Tom Allon, de Blasio, Comptroller John Liu, Council Speaker Christine Quinn, Manhattan Borough President Scott Stringer and Thompson—collected $517,000 in Brooklyn in 2011. That’s more than the $33,000 they received from the Bronx or the $51,000 Staten Islanders donated, but less than came from Queens ($606,000), Manhattan ($1.7 million) or outside the city ($1.6 million).

To date, de Blasio has attracted the most Brooklyn donations, roughly $176,000. Quinn has raised just under $150,000 and Liu just over $115,000. Thompson and Stringer both brought in around $37,000. Allon collected $2,125 in Brooklyn in 2011.

The 11201 zip code in Brooklyn Heights delivered more campaign cash than any other in Brooklyn last year, with about half its $91,000 in donations going to de Blasio. Gerritsen Beach (11234), Park Slope (11215), Gravesend (11223) and Williamsburg (11211) are the only other Brooklyn zip codes to register more than $30,000 in contributions last year. East New York, Crown Heights and Brownsville are among the zip codes to barely register on the money front.

The biggest intermediary for Brooklyn donations in 2011 was developer David Walentas, who oversaw $11,100 in gifts to Speaker Quinn. His son Jed raised money for Stringer.
