The Barna Group has announced a new survey showing that more born-again voters support Democratic candidates this year than Republican ones. Barna's surveys always have to be taken with a grain of salt, and in this case for at least two reasons. First, the born again are not separated by race or ethnicity, and so include a lot of traditional Democratic voters, African Americans especially. Also, the usual polling question ("Do you consider yourself a born-again or evangelical Christian?") was not employed, but some other questions that enabled Barna to distinguish the born again from the evangelicals. And the evangelicals in the survey favor Republicans--though there are a lot of undecideds. The bottom line: This is suggestive, but it would be really helpful if today's Democratic exit polls include the standard evangelical question.
