I have come to the conclusion that National Review is primarily beholden to their big donors and not conservatism at all. They are hired hands to further their big donors interests.
It is just a job for the writers.
Well, opinion magazines usually don't show a profit, so the money has to come from somewhere.
In the beginning it was the Buckleys and old Bob Taft-supporting industrialists from the Midwest, but there aren't many of them left.
But I think it's more a matter of National Review wanting to control the conservative "brand" and fend off competitors for control of the brand.
Also, it may have something to do with living in Manhattan (or for many of the writers, Washington DC).
Anyway, good article. Worth a look.
