OKLAHOMA CITY (NewsNation Now) — There are just two early voting sites in Oklahoma County for its nearly 800,000 residents, and election officials are warning early voters to expect long wait times.

With social distancing reducing the number of voting booths, and the need to disinfect each booth after each voter casts their ballot, Oklahoma County Election Board officials are anticipating some lengthy delays.

“People need to social distance, so we can’t even have as many people, you know, the voting booths are going to be spread out,” said Doug Sanderson, the board’s secretary, told NewsNation affiliate KFOR.

Oklahoma already has one of the shortest early voting periods in the nation at just three days, from Oct. 29-31.

Elections officials in Oklahoma are urging people who want to avoid the polls on Election Day to vote by mail.

“The only way to avoid a line is the vote by mail,” Sanderson said.

Oklahoma voters can request an absentee ballot up until Oct. 27.
