Herman Cain Memoir Hits Top 10 on Amazon.com

'This is Herman Cain' gains popularity After GOP candidate makes press tour

GOP presidential candidate Herman Cain is not only doing better in the polls, but also on best-selling charts.

"This is Herman Cain," Cain's newly released memoir was in the top 10 on Amazon.com Tuesday.

Cain's popularity has increased after Texas Gov. Rick Perry's "Niggerhead" controversy broke over the weekend.

Cain has not been quiet since the news broke and said it was "insensitive" for Perry to have a hunting camp he used with his family known by a racial epithet.
