Herman Cain announces that he is suspending his campaign as a Republican presidential candidate as his wife Gloria Cain looks on during the scheduled opening of a local campaign headquarters on Dec. 3, 2011 in Atlanta.

*The Daily Beast columnist Allison Samuels writes that Herman and Gloria Cain’s marriage had its share of problems over the years, in part due to the former GOP presidential candidate’s attraction to other women.

A friend of one [of] Cain’s two children explained: “It never felt like a real marriage when I was around them. Mostly he was always gone and his wife seemed to be OK with it. Not being together seemed the norm for their marriage, and Gloria didn’t seem to mind. His kids didn’t seem to mind either. ’’

The friend added that when Cain was around, he seemed completely in his own world.

“He was king of his castle and no one questioned him,’’ says the friend. “It was an uncomfortable set-up for an outsider like me to be around. He was so indifferent to everyone. But I liked Gloria. She was warm and kind.”

In other Cain news, the former CEO of Godfather’s Pizza admitted to having used quotes from the movie “Pokemon: The Movie 2000” — specifically the theme song, “The Power of One,” sung by Donna Summer – during several speeches in his run for the White House.

In August during the Republican primary debate in Iowa, Cain quoted “a poet” as having once said, “Life can be a challenge, life can seem impossible, but it’s never easy when there’s so much on the line.”

It wasn’t the only time he quoted from the movie, and several bloggers have been quick to point out his gaffe.

On Saturday, he clarified the source.

“I believe these words came from the Pokémon movie. I’m not sure who the original author is, so don’t go write an article about the poet, but it says a lot about where I am — where I am with my wife and my family, and where we are as a nation,” Cain said, according to the Huffington Post. “Life can be a challenge. Life can seem impossible. It’s never easy when there’s so much on the line. But you and I can make a difference. There’s a mission just for you and me.”

Cain also admittted to GQ in a recent interview that he first heard the song during the Olympics and instantly sparked to it.

“I fell in love with this song, fell in love with how she sang the song and fell in love with the words,” she said. “Committed it to memory. Now, why did I commit it to memory? Because one of the things that I did before I ran for president is I was a professional speaker. Not a motivational speaker — an inspirational speaker. Motivation comes from within. You have to be inspired. That’s what I do. I inspire people, I inspire the public, I inspire my staff. I inspired the organizations I took over to want to succeed.”
