Gov. Andrew M. Cuomo held off an insurgent primary challenge Tuesday night from Fordham University law professor Zephyr Teachout.

With 90 percent of election districts reporting, Cuomo had 61.1 percent and Teachout had 35.1 percent. Randy Credico, a comedian and activist, had 3.78 percent.

In Suffolk County, Cuomo was leading Teachout 55 percent to 43 percent, with 99 percent of the election districts reporting. Credico had 2 percent of the vote.

In Nassau County, Cuomo had a more substantial lead, 65 percent to Teachout's 32 percent, with 86 percent of the election districts reporting.

"Today's outcome is a testament to the progress we have made together over the last four years," Cuomo said in a statement.

Teachout thanked 200 supporters that had gathered at the Hudson Terrace lounge in Manhattan. "This is a campaign that took on the machine," she said.

At 10:14 p.m., The Associated Press declared Cuomo the primary winner.

Still, it was a stronger showing for Teachout, a political newcomer, than insiders had predicted.

Democrats also selected nominees for lieutenant governor, and minor parties chose judicial candidates in Nassau and Suffolk counties.

The AP declared Kathy Hochul, Cuomo's choice for lieutenant governor, as winner against Teachout's running mate, Timothy Wu.

Hochul had 59.2 percent, to Wu's 40.8 percent, with 90 percent of election districts reporting.

Cuomo, who had mostly ignored the challengers, congratulated Teachout and Wu "on running a spirited campaign, engaging in the democratic process and having the courage to make their voices heard."

LI voter turnout

Turnout generally was light on Long Island. Nassau Board of Elections Commissioner William T. Biamonte described turnout in the Democratic primary as "beyond abysmal." He predicted turnout would approach 5 percent.

In Suffolk County, Democratic turnout was 3.56 percent at about 5 p.m., according to the Board of Elections, with 9,555 votes cast. Conservative Party turnout countywide was 15.9 percent, driven primarily by a competitive judicial nominating race in Huntington.

The polling site at Maplewood Intermediate School in South Huntington was empty in the afternoon except for the roughly half-dozen poll watchers. In the 10 hours since the polls opened, only 48 people had voted, poll watchers said.

Voter turnout at Presbyterian Church of Sweet Hollow in Melville had been "slow" all day, a poll worker said. In nearly eight hours since the polls opened at 6 a.m., she said about 50 people had cast votes.

Voter sentiments

Mary Langis, 73, of Melville, was not going to vote for Cuomo for a second term, mainly because of his stance on abortion and because she said he hasn't done enough for seniors.

"I am hoping maybe this will wake him up a little bit," Langis said. "I am very disappointed. He didn't turn out to be what I thought -- like his father."

Marcia Pena Thompson, 82, of Melville, said issues important to her include improving the education system, the economy and immigration.

The retired social worker, who voted for Cuomo for a second time, likes the governor's ideas and policies.

"We need to liberalize our immigration issues and not penalize people for wanting to come here," Thompson said. "We should try to make it possible for people to fit into the system. Fighting them isn't going to help."

Teachout has criticized Cuomo, saying he broke his 2010 promise to clean up corruption in Albany. He has come under fire over news reports that have accused his top aides of interfering with the Moreland Commission on public corruption. Cuomo has denied interfering, saying he and his staff merely provided the commission, which he disbanded, with advice.

Teachout said she voted for herself and her running mate, Timothy Wu, a Columbia University law professor, just after 7 a.m. at a public school in the Fort Greene neighborhood of Brooklyn.

After voting she got a round of applause from poll workers, then posed for a photograph and signed an autograph. "That felt great," she said.

Cuomo, who has tried not to engage Teachout, said he has worked to jump-start the economy and hold down taxes, while pressing successfully for tighter gun control laws and legislation that gave same-sex couples the legal right to marry. He voted Tuesday morning in Mount Kisco, Westchester County.

Cuomo will face Republican nominee Rob Astorino, Westchester's county executive, in November.

Other LI primaries: state Legislature and judgeships

In other races Tuesday, Independence Party voters also picked a nominee for the 2nd Assembly District on eastern Long Island. Thomas Schiliro, 62, of Manorville, a Democrat who also has the Working Families Party line was leading Incumbent Anthony H. Palumbo, 43, of New Suffolk, a Republican who is also on the Conservative Party Line, 126 votes to 114 votes.

In judicial races, there were Independence Party primaries in Nassau for County Court and Family Court.

There were Independence primaries for 2nd and 4th District Courts in Hempstead and a Democratic primary in Long Beach for city court judge.

In Suffolk County, there were Independence, Working Families and Conservative Party primaries for 3rd District Court in Huntington, and an Independence Party primary for 6th District Court in Brookhaven.
