*Whether it was just perfect timing or he’s truly popular, Herman Cain’s memoir reached the top 10 best sellers on Amazon.com.

“This is Herman Cain” was released recently and reached the top 10, as the business-man is in the running to be the Republican presidential candidate.

The book sold so fast that the hardcopy of the book is out of stock until Friday.

In his recounting of life, Cain looks back at growing up in the segregated South, but always looked to the day he would be in the White House.

In the past, his dream was a bit of a long shot, especially with many Republicans doubting him. However, recent polls reveal that he’s a top contender for the position.

Cain’s rise has come at the same time support has dropped for Texas Gov. Rick Perry, whose book “Fed Up” soon created problems for his campaign with its references to Social Security as a “Ponzi scheme” and a “crumbling monument to the failure of the New Deal.”
