DES MOINES, Iowa (CNN) - On the stump, Mike Huckabee boasts about running a clean campaign that steers clear of smearing his GOP rivals.
But now a group founded by some of Huckabee's supporters appears to be doing just that.
The group, Common Sense Issues, launched a series of automated calls Sunday to Iowa Republican voters offering negative information about Huckabee's rivals, and positive information about the former Arkansas governor.
The group's executive director, Patrick Davis, dubbed the calls "personalized educational artificial intelligence," and admitted they are designed to promote Huckabee.
"We believe that Mike Huckabee has the character and the record to put this country on the right path," Davis told CNN, "a path that is healthier physically, fiscally and culturally."
The calls directed Iowa voters to the group’s website, trusthuckabee.com, which allows visitors to sign up to be a Huckabee precinct captain, an important organizing position for the Iowa caucus.
