Gov. Andrew Cuomo’s re-election campaign has more than $15.7 million in cash on hand for the final 11 days of the general election, a filing with the state Board of Elections shows.

Cuomo’s overall haul is practically 16 times the amount that Astorino, the Westchester County executive, has in the bank. He reported slightly more than $1 million in cash on hand earlier today.

Nevertheless, Cuomo has been putting his fundraising advantage to use, spending $8.6 million over the last three weeks, while raising $717,936.

The filing shows that he has transferred $4.4 million to the state Democratic committee, which has largely been used as a surrogate to launch attack ads against Astorino.

Cuomo’s campaign alone has spent $2.3 million on advertising in the last week three weeks, the filing shows. Astorino has spent just over $500,000 during the same time period.

The filing also reveals that the publisher of Cuomo’s book, HarperCollins, paid $2,000 for the one-time use of the campaign’s email list in order to promote the governor’s memoir, “All Thing Possible” that was released last week.

Cuomo returned $10,000 in contributions from Alan Brand, a Long Island man who, along with his son, was indicted on charges of embezzling Medicaid funds. Cuomo spokesman Peter Kauffmann said the contributions were turned over to the state attorney general’s office rather than return the money to Brand.

Cuomo reported $95,479 in in-kind contributions for unspecified “travel” expenditures.

The governor last week traveled to the Caribbean to make stops in the Dominican Republican and Puerto Rico.
