Oz, a Republican, brought celebrity status and high recognition to a crowded primary field when he announced he is running for U.S. Senate in Pennsylvania in November.
He and several other Republicans are seeking to secure the party's nomination to replace outgoing Senator Pat Toomey.
But one person identified as a "veteran daytime producer" spoke out against him in a profile in New York Magazine.
Dr. Oz is dangerous because he believes he's got some divine power," the producer said.
Pennsylvania's Senate race is likely to be one of the closest and most important in the nation.
A Trafalgar Group poll from earlier this month showed Oz winning with 18.8 percent of likely voters backing him.
Still, more than half of voters said they still were not sure who they would vote for. »
