BS. I have posted MANY times the opinions of Buckley on populism and how Buckley got Reagan to agree to keep populists out of power. Back when you pretended to be mainstream Republican you mentioned Ike was your favorite. From Google AI:
Evidence suggests that Dwight D. Eisenhower had a strong aversion to certain aspects of populism, particularly those associated with exclusion and intolerance. He staunchly opposed the populist "Know Nothing" movement, which sought to curb immigration in his time.
Beyond specific movements, Eisenhower's governing style and philosophy, known as Modern Republicanism, emphasized a moderate approach that balanced individual freedom with government assistance where needed. He aimed to navigate "down the middle of the road," avoiding both the excesses of concentrated wealth and the dangers of extreme partisan interests or statism. This approach contrasts with the potentially divisive nature often associated with certain forms of populism.
Furthermore, his actions regarding Senator Joseph McCarthy, whom he reportedly "loathed," suggest a deliberate effort to counter the senator's influence and the brand of populist fear-mongering he embodied, though he chose not to publicly confront McCarthy. This demonstrates a strategic opposition to at least one prominent figure associated with populist sentiment in his era.
In summary, while the sources don't explicitly state that Eisenhower "hated" populism in general, they indicate a clear opposition to specific populist movements and a preference for a more moderate and inclusive political approach, which could be interpreted as a dislike for the negative aspects of populism.
I am FAR closer to Ike than Trump is. It has nothing to do with personality, populism was not GOP until Trump. Buckley died in 2008, so yes, until about a generation ago populists had little power in the GOP. Then people like his disciple, George Will, were kicked out.
