“Giddy” is not exactly a word to describe Gov. Andrew Cuomo — ever.

But Cuomo did seem pleased, if not happy, that his 2014 Republican opponent, Rob Astorino, had failed in his bid for a third term as Westchester county executive. And a day after Astorino’s landslide loss, Cuomo danced on what would appear to be Astorino’s political grave.

“You look at Westchester County, where Astorino was a Trump acolyte and trumpeted it all the time,” Cuomo said Wednesday on a conference call with reporters when asked to analyze the results of the off-year election.

“You’ve spent $4 million, over $4 million and (Democratic candidate George) Latimer spent $1 million and something. And he was trounced. Trounced in a county where the county executive, Astorino, made a point of his relationship with Trump.”

Cuomo interpreted the victories by Democrats in New York as a rejection of President Donald Trump, congressional Republicans and a GOP-backed tax plan on the federal level he has criticized for its potential to have a negative impact on the state.

He predicted this was only the start of a wave for Democrats heading into next year, when he is seeking a third term himself, and reiterated his call for two factions of Democrats in the state Senate to unite.

But Astorino was singled out for specific criticism.

Asked later on in the call if he thinks Astorino will run against him again in 2018 as he seeks a third term, Cuomo in essence wished him the best — and then slammed him some more, calling him a rejected “Trump-ette.”

“If he wants to run, God bless him, whoever wants to run, they can run,” he said. “I think Rob Astorino doesn’t understand what New Yorkers believe. I think his positions as an extreme conservative republican are repugnant to the state of New York.”

Cuomo lamented the state of the Republican Party, too, saying the party has been taken over by far-right politicians.

“There are no more Rockefeller Republicans. This is a party that’s been taken over by the extreme conservatives,” Cuomo said. “They’re against a woman’s right to choose, that doesn’t sell in New York. In the midst of all of this violence, they want to roll back the SAFE act that I passed, the smartest gun safety legislation in the nation, and they want to roll it back.”

The state Democratic Committee, which is under the governor’s control, test marketed an anti-Trump message in the Westchester County race — a strategy Cuomo’s re-election team will most likely re-deploy on a statewide basis next year, regardless of his opponent.

But Cuomo is also under pressure from liberal advocates to broker a truce between the mainline Democratic conference in the Senate and the Independent Democratic Conference. Cuomo on Wednesday in the call pointed to the meetings he’s held to broker peace in the Senate.

Both sides, he said, need to find a way toward compromise, saying “it takes two tango.”

“The two sides should check their egos at the door and unify that this is internal, intramural political fights within the Democratic Senate,” he said. “And it’s about power and prestige and ego, and I don’t care about any of the above. They should unify.”
