The Tulsa County Election Board said it's handling more than 100 new voter registrations and 1,000 absentee ballot requests every day.
There's still time to register to vote and to get an absentee ballot for the general election November 8.
Both can be done online.
"We have the online request available now, at Tulsacounty.org where you can go online and request your absentee ballot, so people are taking advantage of that," said Patty Bryant, Election Board Secretary.
Some of those absentee ballots are already being mailed in, meaning some people have already voted for president, even though it's only October.
The last day to register to vote is October 14.
