Gov. Andrew Cuomo’s re-election campaign on Tuesday revealed in a campaign filing it had raised $8.4 million in the last six months and has a $35 million war chest heading into the re-election contest.

Cuomo’s Republican opponent, Westchester County Executive Rob Astorino, previously revealed he had only a fraction of that money: $2.4 million in cash on hand.

The first-term Democratic governor, considered an adept fundraiser, shows donations from Hollywood moguls like Jeffrey Katzenberg and director Steven Spielberg who each gave $25,000.

John Mack, the former Morgan Stanley CEO who became an adviser for Cuomo’s economic development program START-UP NY, contributed $25,000.

Though the campaign still is in a relatively early phase, Cuomo’s campaign has already spent heavily on television ads, saturating the airwaves soon after the conclusion of the state Democratic Convention in May.

The filing shows Cuomo 2014 has spent a combined $4.8 million in television ads since March.

That figure doesn’t include the money spent by the state Democratic Committee — an entity Cuomo controls — that has also spent heavily on television buys that have primarily featured ads knocking Astorino’s record in Westchester and policy stances.

A spokesman for the state Democratic Committee said the organization had raised $2.1 million over the last six months, spending most of it, ending with a balance of $248,000.

The committee’s housekeeping account raised $1.3 million and spent $776,063, the spokesman said.
