It was a big night for Gov. Andrew Cuomo, who won a decisive victory over his primary challenger, actress-turned-activist Cynthia Nixon.

In the end, Nixon, who got about 34 percent of the vote, didn’t manage to do any better against the incumbent Democrat than Fordham Law Prof. Zephyr Teachout did in 2014, though turnout was up significantly.

Cuomo also saw victory in the success of the rest of his “slate,” as it were. LG Kathy Hochul managed to fend off a spirited challenge from Brooklyn Councilman Jumaane Williams, though he was in the lead for much of the night as the results came in.

It was upstate, particularly Hochul’s home turf of Western New York, that gave her the edge in a race that, early on, the governor didn’t want her to run in, saying he would prefer to see her challenge Republican Rep. Chris Collins, who subsequently was charged with insider trading and opted not to seek re-election in November.

But Hochul persisted, refusing to step aside, and she was rewarded last night.

Williams had one upstate stronghold – Tompkins County, which is home to the liberal city of Ithaca. He won 62 percent of the vote there, with a margin of 2,390 votes.

Also pulling off a very big win was Cuomo’s preferred state attorney general candidate Tish James, the NYC public advocate, who is poised to become the first statewide elected African American woman in New York. She’ll face off in November against Keith Wofford, the first African American man to be nominated to run for AG by the GOP.

Cuomo, oddly, did not attend any victory parties last night or even issue a video statement after his win.

He watched the returns come in while holed up in the executive mansion in Albany, capping an unusual several days during which he declined to speak to reporters after a series of missteps – including a mailer sent by the state Democratic Party that portrayed Nixon as anti-Semitic – that marred his campaign’s final week.

As John Podhoretz wrote in the NY Post: “There’s no way of looking at Gov. Cuomo’s commanding victory — after how badly he handled the stump and his one debate in the last six months — without saying: Damn, he’s good at this.”

The loss of the progressive Nixon, Williams, Teachout (this time running for AG) slate was a big blow to the left, particularly the Working Families Party, which now much figure out what to do about Nixon in the general election.

If she opts not to run, the party will have to pull some legal maneuvers to get her off its ballot line, and then must win at least 50,000 votes for its gubernatorial candidate in November in order to maintain ballot status.

However, there was a silver lining for liberals last night in the stunning rejection of six of the eight former IDC members, who were primaried by insurgent fellow Democrats despite their agreement – brokered by Cuomo – to rejoin the so-called “regular” Democratic conference.

Topping the list of the fallen was former IDC Leader Jeff Klein, of the Bronx, who lost to Alessandra Biaggi, a former Cuomo attorney who also once worked for Hillary Clinton.

Other ex-IDCers who lost last night:

Queens Sen. Tony Avella, who was defeated in a re-match by former NYC Comptroller John Liu; Sen. Marisol Alcantara, going down to former NYC Councilman Robert Jackson; Queens Sen. Jose Peralta, defeated by Jessica Ramos, who once worked for NYC Mayor Bill de Blasio; Brooklyn Sen. Jesse Hamilton, who was toppled by attorney/activist Zellnor Myrie; and Sen. David Valesky, of Syracuse, who appeared to be ousted by Rachel May, his first primary challenger in 14 years, though he didn’t concede and she didn’t declare victory, preferring to wait until all the absentee ballots are counted in this close race.

The only two former IDC members to survive primary challenges were Staten Island Sen. Diane Savino, Klein’s long-time partner; and Hudson Valley Sen. David Carlucci.

Another high-profile upset was the loss of Brooklyn Sen. Martin Dilan to 27-year-old Democratic Socialist and community organizer Julia Salazar, who managed to pull off a decisive victory even though her campaign was plagued by problems – including her misrepresentation of both her education and personal history.

So, though Cuomo, who spent an estimated $25 million of his copious campaign war chest during his campaign against Nixon, must now face off in the November election against Dutchess County Executive Marc Molinaro, the GOP gubernatorial candidate, over whom polls show he has a comfortable lead, he is poised to return to Albany for a third term with a vastly different – and far more liberal – Senate Democratic conference, which just might pull off its latest attempt at winning back the majority.

A bright spot for the Republicans last night, though: Brooklyn Sen. Simcha Felder, a conservative Democrat who conferences with the GOP, won his primary race against liberal challenger Blake Morris, bolstered by strong support in the Orthodox Jewish community.

Also running for governor in the November general election: Former Syracuse Mayor Stephanie Miner, who is running as an independent on the “Serve America Movement” line; Green Party candidate Howie Hawkins; and Larry Sharpe on the Libertarian Party line.

Also worth mentioning:

– Nassau Democratic Chairman Jay Jacobs declared political newcomer Taylor Raynor the victor in the Democratic primary race for the 18th Assembly District seat. She defeated Deputy Assembly Speaker Earlene Hooper, who has held the seat for 30 years.

– Assemblyman Clifford Crouch turned back a primary challenge from his fellow Republican, Nick Libous, son of the late former Sen. Tom Libous, in the 122nd Assembly District.

– Monroe County Democratic Chair Jamie Romeo emerged from a three-person primary in the 136th District to become the presumptive replacement for departing Assembly Majority Leader Joe Morelle, who won a June primary to succeed the late Democratic Rep. Louise Slaughter in D.C.

– In the 133rd Assembly District, Republican incumbent Joe Errigo lost to challenger and current Caledonia village trustee Marjorie Byrnes. Errigo, who served had previously served in the Assembly, was chosen by party leaders to return to office after the death of Assemblyman Bill Nojay in 2016.
