Voter registration is setting record levels this year according to the Texas Secretary of State's Office, but it's giving election workers a lot of extra work to do before early voting starts October 20.

About 15,000 last-minute registration forms came into the Travis County Elections Office on Monday, with another 15,000 expected on Tuesday. The deadline to register for the November election was midnight Monday night.

"There's a lot of unwrapping going on, a lot of big buckets of mail being hauled in from the mailroom," said Tina Morton, public information officer for the Travis County Elections Office. "We're working nights and weekends."

Each registration card must be scanned into the county's electronic system and verified before voters are certified. A few thousand of the new registrations represent address changes, which must be updated in the system as well.

"It is a record year already, we are at 95 percent registered for the eligible voting population in Travis County and that exceeds where we were four years ago," Morton said.

Travis County estimates more than 600,000 voters will be registered this election year. In Hays County, the number exceeds 100,000. In Williamson County, election workers predict the number is more than 278,000. Staffers say the excitement of the primary season and the historic election is driving the record levels of interest.

"This year we knew it was going to be different. We knew we would need more people," Morton said.
