The Republican Party in the United States has undergone significant changes over the years. The shift towards the ideology associated with former President Donald Trump, often referred to as MAGA-ism, can be traced back several decades. This transformation began with the influential conservative figure William F. Buckley Jr.

Sam Tanenhaus, Buckley’s official biographer, discusses this evolution in his new book, "Buckley: The Life and Revolution That Changed America." In an interview, Tanenhaus draws parallels between Buckley and Trump, describing both as media-savvy and wealthy elites who challenged the very establishments from which they emerged.

Buckley, a prominent arch-Catholic from New England, was known for his unconventional friendships, including those with staunch leftists. Despite these connections, he played a crucial role in reshaping the Republican Party into a formidable political force. His efforts were instrumental in engaging Republicans in cultural conflicts, which ultimately paved the way for Trump’s rise to the presidency.

Tanenhaus's book details Buckley’s journey and the impact of his ideas on American conservatism. He argues that Buckley’s legacy is evident in the current political landscape, where the GOP has embraced a more populist and confrontational approach. This shift has been pivotal in the party's evolution and its strategies in recent elections.
