The competition in the Democratic nomination is so close among evangelicals that some researchers and pundits are being driven to prayer.
Recent polls suggest more evangelicals are voting for Sen. Hillary Clinton than Sen. Barack Obama, but most of the polls are still inconclusive.
Pundits still don't know if evangelicals have voted or plan to vote for Clinton or Obama because exit polls do not ask Democrats whether they self-identify as evangelical.
"I keep praying so far my prayers have not been answered that the exit polls would ask the born-again question because then we could resolve this question," said John Green, senior fellow at the Pew Forum on Religion & Public Life.
The Gallup Poll conducted the most recent poll and found a correlation between religiosity and support for Clinton among Democrats. The organization did not distinguish evangelicals from other highly religious voters, but more white religious Democrats defined as those who attend church weekly supported Clinton (46 percent) to Obama (43 percent).
"It's a bit counterintuitive," Green said. "It's interesting because conventional wisdom says they would be for Barack Obama, who speaks so comfortably about his faith."
Scott Keeter at the Pew Research Center said the center's general political polling shows that Clinton is doing a little better among those who attend church at least a few times a year.
CNN exit polls showed that Obama gained more votes from those who have highest church attendance. However, Obama has also led polls among African American voters, who tend to be highly religious, so Green believes the data does not show whether Obama is winning the religious vote.
