Churches and religious voters will play a big role in this year's presidential election.

Many African American and Latino church leaders have been urging their congregations to register, even handing out registration cards during services.

They're also promising to provide transportation to get "souls to the polls."

Meanwhile, the Faith and Freedom Coalition has released its voter guides in key battleground states. They're sending them to roughly 17 million social conservatives.

CBN News Political Correspondent David Brody said the Faith and Freedom Coalition has the potential to make a big impact.

"They've got the cell phone numbers of 13 million evangelicals in this country. Well, guess what? In 2008 they had the cell phone numbers of zero evangelicals. Now it's 13 million," Brody noted.

"Barack Obama's campaign in 2008 had 7 million cell phone numbers of liberal voters so they already had more than Obama's campaign in 2008," he said.

The Faith and Freedom voter guides are being delivered by text message, email, mail, and door-to-door.
