One thing which Stephen A. Douglas was temperamentally incapable of doing was admitting he was wrong. He always believed that 'popular sovereignty' - the core doctrine of the Kansas-Nebraska Bill - was the right solution to the slavery controversy; and even though it had failed to solve much of anything in Kansas and Nebraska, he stubbornly insisted that this was because it had never been adequately tested.

I think, a general anxiety, after the end of the Cold War, to find a new basis for affirming American nationhood. And perhaps another, in plainer terms, is the lure of the approaching Abraham Lincoln bicentennial has been made a resurgence in interest in Lincoln.

It would be pleasant to believe that some of Lincoln's DNA is actively swimming around in somebody's soup, but all the evidence is against it. And of course, there's always the risk that what we might get would be more Robert Todd Lincoln than Abraham Lincoln.

Remember that Abraham Lincoln was a Whig far longer than he was a Republican. As a whole, the Whigs looked upon banks and corporations as a more efficient means of development; the Jacksonian Democrats thought they were the tools of the devil, but Whigs like Lincoln disagreed. During his presidency, Lincoln favored the re-construction of a national financial system, and his most important 'internal improvement' project was the Pacific railroad.

It is possible to have pardon without forgiveness-a murderer can be pardoned by the governor, but that does not mean the victim's family has forgiven him. And there can be forgiveness without pardon.

The best one-volume biography of Abraham Lincoln is still Benjamin Thomas's 1952 biography. David Donald's 1995 biography is a close second, and close enough that if you can only obtain the Donald rather than the Thomas, your book club will still be doing just fine.
