Dante de Blasio, the mayor’s son who graduated from Yale University in May, earned $650 a week from Aug. 1 through Sept. 16 as a policy analyst for his father’s presidential campaign, according to Federal Election Commission disclosures filed late Tuesday.

His salary was just $175 a week less than the campaign’s South Carolina political director, Breanna Spaulding.

Dante’s Yale pal, Ashtan Towles, also worked for the campaign at the same time as the mayor’s son, earning an equivalent salary. Most of the campaign’s $1 million in expenses from July through September were related to the mayor’s travel to early-primary states.

The campaign reimbursed two political accounts, a state and a federal Fairness PAC, for $75,000 in travel costs, digital ads and Web-site work. It also paid a firm controlled by senior adviser Steve Jarding $48,000.

Mike Giaccio, a state Democratic fundraiser who worked for Govs. Eliot Spitzer and David Paterson, received $35,633 for serving as the campaign’s finance director through his own firm.

De Blasio’s trickle of $333,000 in donations during the third quarter came from a smattering of supporters including members of the politically powerful Hotel Trades Council labor union, city workers, heiress Abigail Disney, and the real-estate industry.

The campaign refunded $2,800 that de Blasio pal Steve Buscemi had given for the general election.

Other notable contributions include the maximum $2,800 from Jeffrey Gouveia, president of the Boston-based Suffolk Construction where former de Blasio NYCHA chair Shola Olatoye now works.
