He does very much come at history and politics from a "fallen world" "tragic choices" perspective that's very different from Reagan's. Arguably, that chastened and disillusioned point of view can't muster the enthusiasm to get things done in the real world, though it does hold us back from overconfidence.
Anyway, it's good that Diggins recognizes Reagan's greatness, and it's an indication of what later historians will think. I'm not so sure Reagan's mother was a Unitarian or unitarian, though. "Disciples of Christ" is what the encylopedia says.
Thanks for reasoned comments! I intend to get his book and read it as George Will as piqued my interest.
Here's a clear indication of Ronbo's increasing status in history: just recieved the gratis copies of an article I had published in Automobile Quarterly. The article was on motoring during WWII. They used most of the photos I gave them, but added a couple from their own archives, including a full-page shot of a young Ronbo with Jane Wyman standing in front of a '49 Lincoln Cosmopolitan.
It's a national mag, and with no political agenda. Still, it seems that but a few years ago it would have been controversial to publish that photo. Now, it's normal and without a thought for politics.
Thanks for the ping.
