Clinton's memoir, entitled "My Life," was released at midnight on Tuesday.
Many people waited in long lines to get the book, but in Eau Claire there was no waiting there.
The former President talks about several events throughout his life, including the most prominent, his time in office.
The book has received poor reviews from critics, but it hasn't deterred people from wanting to read his part of history, and pre-orders have passed the two million mark.
It could also affect the Kerry campaign, but one political analyst says it's too early to tell how.
