The tidal wave keeps rolling.
Long Island’s Republican stronghold Hempstead shockingly flipped blue under the weight of the Democratic blue wave in Tuesday’s midterms — as the northern suburbs of Westchester and Rockland counties appeared to be headed the same way.
Voters in the Nassau County county — the most populous in America — bucked Republican rising star John Ferretti from town supervisor, choosing Democrat Joe Scianablo in a stunning three-point victory.
That ran against more than a century of Republican leadership — with Scianablo becoming only the second Democrat to run Hempstead in about 120 years.
Democrats were also on track to take Hempstead’s town clerk job, with Joylette Williams leading incumbent Republican Kate Murray by a few hundred votes Wednesday about a day after polls closed.
Those results mirrored the nationwide midterms, which left Republicans reeling after Democrats snatched majorities in both Congress and the Senate while flipping five governorships.
And they weren’t just limited to Hempstead — the rest of Long Island voted for Gov. Kathy Hochul over Bruce Blakeman, with the Nassau County executive’s own home turf even choosing the incumbent Democrat over him.
District 17 just north of the city turned out for Democrats too, with the battleground territory ousting incumbent Republican Mike Lawler in favor of liberal Cait Conley.
Deeply blue Westchester County was also favoring Democrats for numerous local positions, though some of those races remained up for grabs with votes still being counted Thursday after widespread Election Day ballot machine malfunctions.
The county’s 17-seat Board of Legislators was on track to become all Democrat in the first time in history, after there was only one registered Republican and a registered Conservative Party member left holding seats, with tallies still being counted.
Meanwhile, former Assemblyman Tom Abinanti appeared to be the first Democrat to ever win the supervisor seat in the Westchester town of Mount Pleasant — for years a Republican stronghold in the increasingly Democratic county.
Neighboring Rockland County voted out Republican Sen. Bill Weber — who had received an election day endorsement from President Trump — in favor of Democrat Joseph Rand.
Clarkstown supervisor George Hoehmann was also voted out after more than 10 years in office.
The blame for the widespread losses largely lay on President Trump’s shoulders, according to experts, who said the national environment had become so volatile under his watch that Republicans were being rebuked even on the hyperlocal level.
“Unfortunately for Republicans, local issues were overshadowed by national issues, an affordability message that Democrats delivered to voters,” said O’Brien O.B. Murray, a campaign strategist for both Republicans and Democrats.
“Democrats across New York and the country showed up like President Trump was on the ballot,” he told The Post. “Republican, Independent, and Democratic voters stayed home or used their vote to send a message of displeasure.”
That was echoed by Rep. Tom Suozzi of Long Island’s third district, who handily held his seat over a Republican and said voters came out for the left “not because necessarily they love the Democratic brand, because they are fed up with what’s going on in the country and they want change.”
“They want us to work on the issues that they’re concerned about — affordability, immigration, taxes, crime, and healthcare,” he added. “Then you throw in education and AI, climate change.”
And some experts cautioned that the honeymoon might not last forever.
“Now Democrats are in charge, and they’re going to have to deliver,” Republican and former Suffolk County executive Steve Levy said. “And when they can’t, the public ire is going to be against them.”
“It’s just a matter of time before it lands on the door of the Democrats again.”
