The polls have closed in Oklahoma's Super Tuesday presidential primary election and with all but just a tiny fraction of precincts reporting, Rick Santorum had a healthy lead over Mitt Romney and Newt Gingrich, assuring his victory in Oklahoma.

Voting wrapped up at 7 p.m. Tuesday.

With 99.5% of precincts reporting, Santorum had 33.8% of the vote.

Mitt Romney, who was deadlocked with Newt Gingrich for much of the evening, pulled ahead with 28.1 % of the vote.

Gingrich was a very close third with 27.5%.

Ron Paul got 9.6% of the votes.

The Associated Press says Santorum will get 11 of Oklahoma's delegates, while Romney and Gingrich will get 10 apiece.

At the Republican watch party in Oklahoma City, Governor Mary Fallin said she was pleased that there had been so many campaign visits from the various candidates in Oklahoma and said it was important for the party to come together once the nomination process is done.

"We have to unite behind that presidential nominee and send Barack Obama back home," Fallin said.

Election officials have said turnout was steady over three days of voting.

Santorum had hoped his brand of social conservatism and recent campaign visits would translate to victory in the
self-proclaimed ``reddest of the red'' states.

Mitt Romney, former U.S. House Speaker Newt Gingrich and Texas Congressman Ron Paul also have campaigned in the state in recent weeks.

Tuesday's election was the first statewide election in which voters are required to show proof of identification before voting under a new law approved by voters in 2010, but Oklahoma Election Board Secretary Paul Ziriax says the new requirement has posed few problems in recent special elections.
