Yep
National Review got poisoned
And Wm F Buckley himself was the one who administered the poison, turning on Sobran, Buchanan and paleos in general.
From what I know his sister Priscilla was the one who ran NR when it was worth reading. Bill didn’t do much other than act as the front man. When Priscilla retired as editor and Bill made decisions it started becoming the wreck it is today.
