Although 12 candidates have entered the Republican presidential race so far, only Gov. Ron DeSantis of Florida is polling anywhere close to Donald Trump. What does DeSantis actually believe? How has he governed? And what case will he make to Republicans to vote for him over Trump?To answer those questions, I wanted to spend some time reading DeSantis in his own words. So I invited Carlos Lozada — the Pulitzer Prize-winning former book critic for The Washington Post, current Times Opinion columnist and the author of “What Were We Thinking: A Brief Intellectual History of the Trump Era” — to join me. Lozada has read many, many books by and about Republican politicians, including DeSantis’s two books, “Dreams From Our Founding Fathers: First Principles in the Age of Obama” from 2011 and “The Courage to Be Free: Florida’s Blueprint for America’s Revival,” released this year.We discuss DeSantis’s striking definition of — and rhetorical assault on — “elites,” why his campaign book makes no effort to showcase bipartisan credentials, DeSantis’s awkward transition from a Tea Party figure to MAGA crusader, what DeSantis has actually done as governor of Florida, why Florida’s Covid record is such a cornerstone of his political appeal, what DeSantis means by “wokeness” and why he’s waging a “war” on it, the surprising absence of major economic ideas from his book, how he is trying to differentiate himself from Trump without alienating Trump voters, whether his aggressive actions toward Disney will backfire and more.Mentioned:"America's Ruling Class" by Angelo CodevillaDreams from Our Founding Fathers by Ron DeSantisThe Courage to Be Free by Ron DeSantisHow To by Randall MunroeBook Recommendations:Personal Memoirs of U.S. Grant by Ulysses GrantAn Hour Before Daylight by Jimmy CarterAll the Best, George Bush by George H.W.
