Yes, I absolutely recommend it. It gets a near A+. It is a great book for political junkies, because its focus is on politics. As a teaser, Lincoln to win the presidency had to add to the Yankee abolitionist base, the German Protestants (while keeping the nativist and temperance vote, which was tricky), and assorted moderate business oriented Whig types, who did not want to disrupt their Southern markets, in order to grab Illinois, Indiana, and most importantly, Pennsylvania, the latter of which had a long history of voting for the Dems. How he did it is fascinating.
