Although the book, named Decision Points, is not to be released until November 9, details from the text have been leaked a number of times.
There is still some debate at this stage as to how the book's publication could affect the party's following and reputation within its core voters. Some Republicans, according to author Matt Latimer, argue that the book could help the Republican party by reminding people of all the things they liked about Bush.
Democrats, on the other hand, generally welcome the memoir - including its November release date - because many believe it will help them too by putting voters' faith in Republicanism in doubt.
