Conservative radio kingpin Rush Limbaugh, 53 who has announced his speration from wife Marta in early June, is dating CNN anchor Daryn Kagan, 41 a spokesman for Limbaugh has confirmed to us.The two were spotted at a party Limbaugh co-hosted at a New York restaurant, where guests included VP Dick Cheney, NY Gov. George Pataki and Sen. Bill Frist.The coupling came as a surprise to some friends who consider the Atlanta based Kagen as part of the liberal media axis and a feminist-but then again, opposites attract. Kagen, who has been with CNN for 10 years, hosts 'CNN Live Today.'
