WASHINGTON - Republican presidential candidate Herman Cain is not the type of person who would sexually harass women, his wife Gloria Cain, said in excerpts of a Fox News interview released on Sunday.

Cain's wife of 43 years has remained hidden from public eye as her husband seeks the party's nomination to run against President Barack Obama in 2012. She addressed the allegations that have roiled her husband's campaign in a rare interview.

"You hear the graphic allegations and we know that would have been something that's totally disrespectful of her as a woman. And I know the type of person he is. He totally respects women," Gloria Cain said.

"I'm thinking he would have to have a split personality to do the things that were said," she added in the interview to air Monday on the Fox program "On the Record with Greta Van Susteren."

Four women have made allegations of sexually inappropriate behavior by Cain, including two who settled harassment claims while he was president of the National Restaurant Association.

Cain, a former business executive who has never held public office, has repeatedly denied the sexual harassment accusations.

A Reuters/Ipsos poll last Thursday and Friday, found Cain, with 20 percent support, was second to former Massachusetts Governor Mitt Romney, who polled 28 percent among Republicans.
