OKLAHOMA CITY - Voters heading to the polls for early voting in next week's Oklahoma Primary Election may need to take note of some of the changes to voting laws in the state.

Voters need their voter ID card or a government issued, state drivers license or ID. The election office says you'd be surprised how many people don't realize their driver's licenses are expired until they forget their voter ID card.

"Simple, fast, easy." Stephanie Germany summed up her voting experience Monday.

Early voting is easy if you're prepared. Germany and her husband, Anthony, were in and out in under 15 minutes.

"Just show up, you'll fill out a simple form, name date of birth," said Oklahoma County Election Secretary, Doug Sanderson. "Show us your ID and it's as simple as that."

But Sanderson says it may not be this easy on Tuesday.

"They may be lost on election day," Sanderson said.

That's because Oklahoma County sent out 382,000 new voter ID cards, telling those already registered, their polling site has changed. Sanderson says the redistricting must happen every 10 years because of the U.S. census.

"We've gotten back 70,000 undeliverable," said Sanderson.

A simple call ahead to the election office and an expiration date check on your photo ID will save voters from any hiccups on Super Tuesday.

"Get out and vote, go out and vote," Lt. Governor Todd Lamb said Friday after casting his vote.

Every time a vote is cast the machines keep tally. Around 400 Oklahoma County voters took advantage of early voting Friday. The ballot you fill out won't go into a machine, but will be a provisional one. Oklahoma County says all provisional ballots will be counted in the total votes, after each ballot is verified and the voter who filled it out is checked out.

The Oklahoma County Election Board is open for early voters on Saturday from 8 a.m. to 1 p.m. or Monday from 8 a.m. to 6 p.m. Voting takes place the day of on Tuesday, 7 a.m. to 7 p.m.
