Officials found inaccurate counts in 131 precincts, including one that had an error by 50 votes, the Des Moines Register reported on Thursday.

Chad Olsen, the party’s executive director, told the Register that the results showed "a split decision." The final tallies, exempting the eight precincts that will not be tallied, were 29,839 for Santorum and 29,805 for Romney, according to the Register.

The Santorum campaign said the change in results could change the narrative of Romney as a front-runner.

"The narrative for a long time has been that Mitt Romney was 2-0," Spokesman Hogan Gidley told CNN on Thursday. "And if these results are true and Rick is ahead by 34 votes, then that's not the narrative anymore. There have been two states, two different victors."
