Those races were too early to call as of 8 p.m. ET.

The Cybersecurity and Infrastructure Security Agency, the country's top tech wathdog, is in touch with officials in Northampton County, Pennsylvania, over a glitch that gave voters inaccurate receipts for whom they voted for, an agency spokesperson said.

County election officials said at an Election Day news conference that the issue didn’t actually change voters’ selections and affected only a single race, a retention race for the state’s superior court.

In a call with reporters Tuesday evening, a senior CISA official said the agency had not seen evidence that the issue was more than a glitch.

“We continue to see no deliberate nefarious activity that would cause that should cause anyone to question the security, integrity or resilience of the election,” she said.

NBC News has tracked a variety of minor issues affecting some polling locations, all of which are common on election days. In Hinds County, Mississippi, a judge ruled polls could stay open until 8 p.m. because of ballot shortages.

Women and younger voters in Ohio strongly backed a ballot measure that would enshrine the right to an abortion in the state's constitution, the NBC News Exit Poll of early and Election Day voters found.

Three-quarters of voters under age 45 cast ballots for "Yes" on Issue 1, which supports abortion rights. Voters ages 45 and older, however, were evenly split on the issue.

Among young voters, a majority of both men and women voted to support the ballot measure. But among older voters, men were more likely to vote "No," while women were more likely to vote "Yes."

Shortly after polls closed, NBC News characterized the results as too early to call, with "Yes" leading.

The Kentucky governor's race is too close to call.

Democratic Gov. Andy Beshear is leading, NBC News projects.

Republican Russell Coleman defeated Democrat Pamela Stevenson in Kentucky’s race for attorney general, NBC News projects, keeping the office in GOP hands after a campaign focused on supporting law enforcement and opposing the Biden administration.

Kentucky’s race for governor is too close to call, but a positive sign for Democratic Gov. Andy Beshear is emerging in the counties that are nearly done counting their votes. He’s running slightly ahead of his 2019 vote share so far in those counties — and, of course, Beshear won the governorship in 2019.

Take Bell County, where 29 of 30 precincts are in. Republican Daniel Cameron leads Beshear there so far, 59.8% to 40.3% — but that’s a county where Beshear got only 36.5% of the vote when he narrowly won statewide in 2019.

Another example: Taylor County, where 18 of 20 precincts are in. Again, Cameron leads: 59.2% to 40.8%. But again, Beshear is running ahead of his 2019 vote share in the county (36.9%).
