Evangelical Christian voters have had a strong political and social force in presidential elections for years.

This year, however, showed significant voting changes.

Republican red states turned blue, as Democrats beat Republicans in the Senate. As a result, some Christians are concerned about the combination of President-Elect Obama with a Democratic majority in Congress.

"We're going to have some setbacks here," Al Mohler of the Southern Baptist Theological Seminary said. "We're going to have some real days of disappointment. I think we need to be prepared for that."

Mohler's main concerns are centered on moral issues like abortion and same-sex marriage. He fears Republicans will let go of their stance against these issues to gain more common ground.

"I think there's a real threat here that the Republican Party could decide to say to Conservative Christians, 'there's the door. We're going to move in a different direction,'" he said.

Still, some conservatives believe a liberal administration could actually strengthen the church body.

"If [President Elect Obama] implements the policies that he says that he believes," Wendy Wright of Concerned Women for America explained, "Many people in America...may be shocked enough that we'll see the pendulum swing the other way."

Rebecca Hagelin of the Heritage Foundation explains that the more liberal policies are established, the more likely it is for the "Religious Right" to rally together against them.

"Nothing unites Christian conservatives more than a common enemy, and here the enemy is a radical liberal agenda," she said.
