At the same time, some evangelical Christian voters are sticking close to more traditional, conservative political roots. Last month, tens of thousands of Christians rallied on the National Mall, in response to Fox news host Glenn Beck’s call for a return to America’s religious values.

President Barack Obama has long sought to open a dialogue between his administration and evangelical religious leaders, and he has even found common ground on some issues with conservative groups like the Southern Baptist Convention and the National Association of Evangelicals.

But even though Obama may have won over some religious leaders, he’s losing the battle to win over their congregants.

Though several moderate to conservative evangelical pastors support the president, polls show that a significant percentage of conservative Christians remain skeptical about Obama’s sincerity when it comes to the values that he says they share, and many say they doubt his faith.

Joel Hunter, one of Obama’s religious advisers, who has served on the President’s Advisory Council on Faith-Based and Neighborhood Partnerships, blames a coordinated campaign to spread disinformation about the president, undermining his efforts at outreach to evangelicals. That, he said, leads to suspicions among average conservative churchgoers who suspect Obama is trying “to enlist good people for their sinister causes.”

For every instance of religious moderate leaders supporting Obama on certain issues, “there is this other equal and opposite reaction [from the congregation] that says, ‘Well, it’s all a trick,’” said Hunter, the pastor of Northland, A Church Distributed in Longwood, Fla., and author of “A New Kind of Conservative.”
