The extensions will likely result in a delay in results from these critical swing states, further prolonging the announcement of the election’s victor.

In Texas, Hidalgo County joined Upshur County in becoming the second county to keep its polling locations open an extra hour on Tuesday, until 8 p.m. CT.

The Hidalgo County Elections Department said in a news release that 10 of the county’s polling places experienced technical problems because of “laptop check-in issues.” All 74 voting locations will be open for an extra hour.

“Making sure our voters have the opportunity to cast their ballot is our utmost priority,” Elections Administrator Yvonne Ramón said. “Extending the closure of the polls to 8 p.m. will provide that opportunity to the voters of Hidalgo County.”

Texas voters in Upshur County will also have an additional hour to cast their ballots. A state district judge extended voting hours on Tuesday morning after “polling equipment issues” led to voting delays of close to 90 minutes.

Newsweek reached out to the Hidalgo County Elections Department for comment but did not hear back before publication.

North Carolina extended voting hours at eight of the state’s polling locations in Sampson, Warren, Cabarrus and Guilford counties.

The polling site in Sampson County saw the longest voting-time extension, an additional 45 minutes, making it the last poll to close in the state, at 8:15 p.m. ET. Another site in the county was given 24 extra minutes by the North Carolina State Board of Elections (NCSBE) to remain open.

In Cabarrus County, the two locations will have an extra 17 minutes and 39 minutes, respectively. Cabarrus County officials said one of its sites opened late “due to an issue with the onsite printer.” According to NBC News, a location in Sampson County faced a similar problem.

Three locations in Warren County will remain open until 7:55 p.m. ET, while the location in Guilford County will remain open for 34 extra minutes, until 8:04 p.m. ET.

The NCSBE told Newsweek results will not be released until all the polls are closed. “The last polling place is scheduled to close at 8:15 pm,” an NCSBE spokesperson said in an email. “Results should be released shortly thereafter.”

All polling sites in Spalding County, Georgia, will remain open until 9 p.m. ET after a judge ordered the extension in response to voting machines crashing on Tuesday morning.

Voters in line before 7 p.m. can use the regular machines to vote. Voters who arrive between 7 and 9 p.m. will cast provisional ballots, which will not be tabulated until Friday. According to WSB-TV, election officials said the information was incorrectly loaded onto poll pads, preventing machines from working properly.

Georgia’s largest county, Fulton, will have its election results delayed because a water pipe burst at one of the county’s absentee-by-mail processing operations.

Election officials said no ballots were damaged, but results from the county, which contains Atlanta, will not be available until Friday.

Texas, North Carolina and Georgia, which all voted for President Donald Trump in 2016, are considered toss-up states. On Election Day, FiveThirtyEight shows Joe Biden ahead in North Carolina and Georgia by less than 2 percentage points and Trump ahead in Texas by 1.1 points.

Late Tuesday, a Nevada judge extended the poll-closing deadline by an hour at 30 locations. As long as voters are in line by 8 p.m. PT, they will still be able to cast their ballots.

In South Carolina, a printing error at one county will delay final results. More than 13,000 votes in Dorchester County will have to be counted by hand because of misprinted bar codes on the mail-in ballots. Dorchester County Elections Commissioner Todd Billman said during a news conference that while the error won’t affect any votes, they will not be counted on Tuesday.

Billman said the county’s full results will be available Friday.

Dorchester County went for Hillary Clinton four years ago, but Trump won the traditionally red state, gaining nine of South Carolina’s electoral votes.
