Barna views evangelicals as a more socially conservative subset of "born agains." Evangelicals, they say, represent about one-fifth of all born again Christians, and the larger group cast approximately half of all ballots in 2004.

"Understanding the faith-driven vote is as complex as assessing the nation's spiritual profile," commented David Kinnaman, president of The Barna Group. "Around election time, Christian voters - and in particular, evangelical voters - the power and perspectives of evangelical voters are stereotyped. If you use a belief-based definition of evangelicals, which is a means of definition that most evangelicals would be comfortable with,you discover that the size of the evangelical voting group is actually quite small. It represents only about 1 out of every 11 voters."

Kinnaman denies that evangelical voters are splintering over issues such as abortion and homosexuality.  However, "concerns about same-sex relationships are less unifying and less troublesome to the broader born again constituency. Born agains are far less concerned about homosexuality than they are about abortion."

Evangelicals of all parties say their

top concern is abortion (94%). This was followed by the personal debt of Americans (81%), the content of television and movies (79%), homosexual activists (75%), and gay and lesbian lifestyles (75%). Evangelicals were more likely than other adults to be concerned about illegal immigration, but they were less worried about HIV/AIDS than virtually any other segment of the population. One of the most significant differences of opinion expressed in the survey was the skepticism evangelicals harbor toward global warming (only 33% identified it as a major issue) compared to the rest of the population.

Barna classified about two out of every five registered Democrats and roughly three out of every five Republicans as a "born again."

Barna conducted the surveys that formed the basis of their report in January 2007 and July-August 2007.
