(CNN) - The already-contentious North Carolina Senate race took a brutal turn Wednesday after incumbent Sen. Elizabeth Dole released a television ad suggesting challenger Kay Hagan is "Godless."
“A leader of the Godless Americans PAC recently held a secret fundraiser for Kay Hagan,” the 30-second ad says before showing clips from members of the group declaring God and Jesus do not exist.
“Godless Americans and Kay Hagan. She hid from cameras. Took godless money,” the ad's narrator also says. “What did Kay Hagan promise in return?”
The ad ends with an unidentified female voice declaring, "There is no God."
The Dole campaign says it's basing its charge on Hagan's attendance at a fundraiser that was in the home of an advisor to the Godless Americans’ political action committee, a group that promotes rights for atheists.
In a conference call with reporters Wednesday, Hagan said she has never heard of the Godless PAC "before Lydie Dole sent out a press release on this," and said the fundraiser in question had more than 40 hosts, including Sen. John Kerry. She also said she has contacted her lawyers to issue a cease-and-desist order on the commercial.
"I am absolutely appalled at Elizabeth Dole's vile tactics," Hagan said. “This is politics of the worst kind, and I know it has been rejected by North Carolinians at every level. It is so unbecoming of a woman like Elizabeth Dole. This is a fabricated, pathetic ad."
Hagan went on to strongly defend her faith: "I am a Sunday school teacher, I am an elder at First Presbyterian Church in Greensboro, my family has been going to this church for over 100 years, I have raised my children there. I have been involved in youth missions."
A National Republican Senatorial Committee spokesman defended the ad.
"Kay Hagan recently attended a fundraiser held in the home of a founding member of the Godless Americans PAC," Online Communications Director John Randall said. "Now Hagan believes it is unfair to associate her with the group even though the soiree raised her thousands of dollars in campaign cash. I guess money is more important to Hagan than principles."
Recent polls suggest Hagan - a Democratic state senator from Greensboro who began the race at a major money disadvantage to Dole - is now leading the incumbent slightly with only days remaining before Election Day.
