There's a lot of good comments pointing out potential flaws in his argument, but responding to yours since it's the most recent...
You're preaching to the choir. I disagreed with him at the time I read it and still do. The single party south is a "great" example of what happens when primaries become what matter.
On the other hand, the current political polarization and problems are due to the old system, so conceivably changing the structure could change things for the better. It's just fun to consider.
I'd also note that he worked in Congress (not elected) for awhile and taught for a couple decades, so his 160 page book anticipates a lot of the obvious criticisms thrown out here.
