Numerous Rockland County Republican elected officials in February previewed the controversial video put out by the party that critics have branded as anti-Semitic for warning of a “takeover” by the Hasidic Jewish community, The Post has learned.

The early look at the digital attack ad — some six months before its public release — shows that the targeting of the ultra-orthodox community was a well-thought-out, deliberate strategy, sources said.

No one in the room objected to it, a GOP source who attended the February meeting told The Post.

“The video was introduced by Lawrence Garvey [the county GOP leader] and played in front of a room of 20-35 people. The entire video was played with Ed Day [the Rockland County executive] there,” the source said.

“We were told we are raising money for the county legislators’ races and unveiling a strategy and we saw the video then. I thought it was a bad strategy,” the source said.

But the source didn’t raise an objection at the time.

The GOP’s “A Storm is Brewing” video blames Hasidic Jews for housing over-development in the suburban county.

“Aaron Wieder [a Rockland County legislator]and his Ramapo bloc are plotting a takeover,” it says.

The caption of the video also says: “The stakes have never been higher. The future of our County, our communities, and our homes hangs in the balance of this year.

“If they win, we lose!”

The Rockland County GOP took down the video Thursday following a firestorm of criticism — including from the Republican Jewish Coalition, state Attorney General Letitia James and Gov. Andrew Cuomo.

“This video is absolutely despicable. It is pure anti-Semitism, and should be immediately taken down. The Rockland County Republican Party is an embarrassment and has no place associating itself with our party,” the RJC said in a tweet.

County Executive Day on Friday denied he had anything to do with the video.

“This is not my video and it was not my place to approve or disapprove of anything produced by the Rockland County Republican Committee,” Day said in a statement.

“I have already issued a clear, unequivocal response to this video, answered numerous inquiries from my constituents and in point of fact, played an integral role in making sure it was taken down.”

But sources point out that campaign literature and ads that Day put out for his 2017 re-election campaign included the same language used in the discredited party video.

“Now those who threatened our way of life have registered thousands of new voters looking to takeover Rockland and undo the work we’ve done. A STORM IS COMING ….,” the Day 2017 campaign piece said.

One of Day’s ads in that race warned, “A Storm is Brewing in Rockland.”

Rockland County Dems said the video ad posted on Facebook was just the latest anti-Jewish smear by Republicans.

“Between rabid videos and divisive facebook posts, Ed Day has made a career out of trying to divide people. He’s a hate monger, not a leader,” said Rockland County Democratic Committee spokesman Joseph Coe.

Garvey declined comment.
