FANNIN COUNTY, Texas — March 5 is Super Tuesday, when Texans and Oklahomans will make their choice for presidential candidate in the presidential primary elections.

The polls open at 7 a.m. Tuesday, and county clerk employees are trying to make sure voters know what they're doing before they cast their ballots.

State officials in both Oklahoma and Texas have online information portals to give citizens a preview of what's on the ballot in their area, and also information about polling places.

Polls in both states are open until 7 p.m. Tuesday. Registered voters need only to show a valid state-issued photo ID card to participate.

In Fannin County,  there will be fewer polling places for Democratic voters.

"Because there weren't enough election workers to come out and work the polls, they will be combined into 12 polling places instead of the 17, so it's important to know where you're going before you set out to go vote tomorrow," said Fannin County Clerk Tammy Biggar.

KTEN-TV and will have comprehensive Super Tuesday coverage on the air and online.
