This is quite a thin book, but with an engaging writing style. It seems to glass over why Taney made such a seemingly radical decision and why he was able to get 6 others to affirm it. Little treatment of his relationshiop with the Catholic church or even what he thought of blacks as individuals.
Rather jarring discussion of George W. Bush and Rumsfeld, where he takes the predictable liberal positions, while excusing Lincolns' abuse of arresting a sitting Ohio congressman. Not one word about controversy of whether Taney had been targeted for arrest by Abraham Lincoln.

This book whets your appetite for more and is good for someone who doesn't have the time to read a more detailed study.
