ATLANTA (AP) _ Former CNN talk-show host Bobbie Battista has taken a job running the media campaign for Bob Irvin, a north Atlanta Republican running for Democratic Sen. Max Cleland's seat.

Battista left her job as host of the afternoon ``TalkBack Live'' show last year and started a public relations firm, Atamira Communications. Another CNN veteran, former producer David Bernkopf, also runs the firm and will work on the Irvin campaign.

``We'll be doing his media strategy and media placement, but we're really involved in all aspects of the campaign,'' Battista said Tuesday.

Irvin is challenging Rep. Saxby Chambliss for the Republican nomination. He has served 14 years in the state House, but is considered a long shot for the party nod.

``He's totally an underdog. We acknowledge that,'' Battista said. ``But we feel Saxby Chambliss is vulnerable on a number of points, and we're excited about getting this thing started.''
