OKLAHOMA CITY (AP) - Polls are open for Oklahoma voters to cast ballots in this year's presidential primary contest.
Polls opened at 7 a.m. Tuesday and remain open until 7 p.m. Oklahoma has 40 of the 419 delegates up for grabs as one of the 10 states holding a Super Tuesday primary election.
All four GOP candidates have visited the Sooner State in hopes of courting voters, and Rick Santorum made a last-minute stop to the state over the weekend.
Although the Republican primary has attracted the most attention, Democrats are also electing a presidential nominee. Four candidates are challenging President Barack Obama for the nomination.
Tuesday's election is the first statewide contest in which voters are required to show proof of identification before voting under a new law approved by voters in 2010.
