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.
