Following up on the earlier post, I've had a slew of readers write in to ask me what the other best political book is.

To recap I said that David Frum was the "author of one of the two best political books I’ve ever read."

So what's the other one? Michael Lind's Up From Conservatism.

Idiosyncratic, penetrating, erudite, highly original, with shards of auto-didacticism cutting through it, and all strung tightly over a rock-solid narrative.

It's a must-read for anyone who wants to understand American politics.
