National Review changed and went to the dogs after WFB died.
William Buckley was for several decades the leading light of American conservatism. While he "excommunicated" people who he saw as antithetical to responsible conservatism, e.g., isolationists, Birchers, Objectivists, he recognized that there were three pillars to conservatism: economic, cultural, and defense. Buckley tried to balance these factions. The liberal converts were anti-Communist but also closer to a Theodore Roosevelt or Richard Nixon model of big government activism than to Buckley style conservatism. Their view became dominant at National Review.
By the time Trump announced his Presidential campaign in 2015, the National Review writers thought the old methods would shut down the former liberal from New York. They failed and the more alert never Trumpers like Glenn Beck defected to MAGA.
