Thanks for the link. The article is dated 2002 and ‘Team of Rivals’ was published in 2005, so hopefully she got her “mechanical processes” straightened out in time for that book.
On the other hand, to get another view of Doris Kearns Goodwin, you might read an earlier FreeRepublic thread about her speech at the Gettysburg 150th Commemoration:

According to that thread, she used the occasion to push her own views on something other than the historical occasion she was invited to speak about. It doesn’t matter to me what her views on the subjects she talked about were; it just seems inappropriate for the occasion.
If she sticks to actual history in the book you chose and doesn’t slant the book, it might be worth a read.
