Texas Rep. Ron Paul has won the Values Voter Summit's presidential straw poll, while Herman Cain and Rick Santorum placed second and third, respectively.

At the three-day event, which was sponsored by the Christian conservative groups American Family Association (AFA) and Family Research Council (FRC), Paul received 37 percent of the survey, or 732 out of 1,983 votes cast, the AP reported.

Former Godfather's Pizza CEO Herman Cain came in second with 23 percent, or 447 votes, while former Pennsylvania Senator Rick Santorum rounded the top 3 with 16 percent, or 323 votes.

All three presidential hopefuls spoke at the event. In addressing the crowd on Friday, Santorum chided Obama for no longer defending in federal court the Defense of Marriage Act (DOMA) – calling it an “abomination” – and for allowing gay couples to marry on military bases in states where it's legal now that “Don't Ask, Don't Tell” has been lifted, which he labeled a violation of DOMA. He also pledged to fight marriage equality “in every state to make sure that marriage remains between one man and one woman.”

In announcing the results of the poll on Saturday, FRC President Tony Perkins said it was too early in the process to determine who will be the GOP nominee.

“You saw the response – Herman Cain had people on their feet; Rick Santorum connected with people,” Perkins said. “I think there's still the hearts and the minds and the passions of the 'values voters' are still there to be won.”

Texas Governor Rick Perry placed fourth in the survey with 8 percent (167 votes), Minnesota Rep. Michele Bachmann, who earlier this year won the Iowa Straw Poll, placed fifth (8 percent/157 votes) and former Massachusetts Governor Mitt Romney finish sixth with 4 percent (88 votes).
