Today marks a big day for voters in 10 states; it's Super Tuesday.
Voters will choose which Republican candidate they want to see on the ballot in November. More than 400 delegates for the national convention are up for grabs in today's election. The latest polls show Rick Santorum with a lead of more than 10 points in Oklahoma, where 43 delegates are on the line.
At 7 a.m. 262 voter precincts will open for voters in Tulsa County. There are a few changes that voters should be mindful of before you head out to the polls today.
* Don't leave the house without your state, federal or tribal government issued I.D. A new law passed by the legislature in July requires all voters to present their I.D. before they vote. Name, photo and expiration date must be visible on the I.D. A drivers license, passport or military I.D. cards will be accepted.
* Oklahoma is a closed primary which means voters can only vote for their party's primary. Registered Republicans vote for their candidates and Registered Democrats will vote for theirs. Registered Independents may not vote in the primary.
* In order for a vote to be counted correctly the ballot box must be filled in completely. Check marks will not be counted. Members of the Tulsa County Election Board say voters should request a new ballot from the Precinct Officials if they make a mistake while marking the ballot box.
Polls will remain open until 7 p.m.
