The Oklahoma Election Board says the number of registered voters in the state has fallen to just under 2 million.
Election Board Secretary Paul Ziriax released the agency's annual voter registration statistics Wednesday. They show the state has 1,978,812 registered voters including 885,609 Democrats, 854,329 Republicans, 238,870 independents and four Americans Elect registrants.
The total is down slightly from just more than 2 million registered voters in the state in 2012.
The days for early voting are changing in Oklahoma, thanks to a new state law.
Beginning this week, voters can cast in-person absentee ballots at their county election board offices on Thursday and Friday before an election.
Early voting on Saturdays will be held from 9 a.m. to 2 p.m., but only for state and federal elections. Because next week's election is a special election, not state or federal, there will be no early voting on Saturday.
Previously, early voting days were Friday, Saturday and Monday. The new state law took effect last week.
