former President Donald Trump, Judy# Woodruff explores what another Trump## nomination and presidency could mean for# the Republican Party and for the country. It's part of her series America at a Crossroads. JUDY WOODRUFF: It's not even February,# and former President Trump appears## to be on his way to sewing up his third GOP# nomination to the highest office in th DONALD TRUMP, Former President of# the United States (R) and Current## JUDY WOODRUFF: After wins# polls show him leading in# South Carolina and beyond. Elected Republican leaders are scrambling# to climb on board. Texas Senator John Cornyn## joined over half the GOP members of the# Senate and most of those in the House. REP. MIKE JOHNSON (R-LA): I have# endorsed him wholeheartedly. SEN. LINDSEY GRAHAM (R-SC): I think he's SEN. TIM SCOTT (R-SC): We need Donald Trump! JUDY WOODRUFF: But not all those in Republican# and conservative circles are joining including "Atlantic" magazine writer David Frum,## former speechwriter for President George# W. Bush and a longtime Trump critic. DAVID FRUM, Senior Editor, "The Atlantic":# Trump has -- he's got some skills,## and one of his skills is understanding# where the pain points are in people,## that -- the things that make him upset,# both his friends and his enemies. How do## you make your enemies upset? Because it's# often a great asset or a reso politician like him to have upset opponents,# to make the opponents crazy with rage too. JUDY WOODRUFF: How does he fit into the tradition# of conservative thought in the United States? DAVID FRUM: If conservatism means protecting# things that are precious in America,## being mindful of the hazards of# change, setting limits on power,## setting limits on appetite, well,# Donald Trump isn't any of those things. Donald Trump is exactly the person and exactly# the thing that conservativ sought to exclude from power. The whole# point of conservative politics has been## that you want to have power distributed, you# want to have power decentralized, you want to## make sure that the people who come to power are# people who both understand the constitutional## restraints on power, but also have the personal,# the character restraints on their own appetites. The anger and rage, the desire to target,# the willingness to use methods that are## anti-constitutional, the fascination with# violence, these are characteristics of## a different kind of politics than the kinds of# politics in the past we have called conservative. JUDY WOODRUFF: How do you explain the# loyalty that Donald Trump has today? DAVID FRUM: Well, we have seen that kind of# loyalty before in state-level politicians,## Mayor Curley in Boston, who somehow# got the support of a certain segment## of Irish Catholic Boston, Huey Long in Louisiana. What these kinds of leaders do is they associate# their hurts and grievances with other people's## hurts and grievances, and they use hurts# and grievances as permission to break rules,## and because they have convinced people# that the people who are enforcing the## rules are your cultural enemies.# And even if I did break the rule,## the fact is, you're still -- I'm# on your side and they're not. I don't think we have ever seen this before with a# federal -- succe I want to speak to hurts and grievances across# the whole culture, across the whole country,## and everyone who tries to enforce# rules on me is an enemy of yours. JUDY WOODRUFF: For someone who has been# at the center of conservative thought,## of watching conservatives, watching the Republican# Party progress over time, tackle tough issues,## do you feel that you should have seen# something like Donald Trump coming along? DAVID FRUM: I did my grieving for# my Republican Party in 2010, '11,## and '12. So I'm now deep into my widowhood.# I can think about this pretty I went to Tea Party rallies and I said,# not only do I not recognize this. Actually,## on second thought, I do recognize this and# it's everything I'm against. So that was## hard. But when Trump came along, look, I was# shocked because he was so personally wicked. But I was not shocked in# that this was a completely## different thing from what I'd been seeing before. JUDY WOODRUFF: There's an animosity, a# personal nat people feel now about politics. What is the# effect that Donald Trump is having on that? And if he were reelected,# what effect would it have? DAVID FRUM: Well, I wonder whether there's really## more division in the country today# than at other Remember the feeling about Vietnam and the draft.# I bet families had a tumult sittin dinner in 1969, '70, and '71. Debates over civil# rights and the integration of schools in the early## 1950s and early 1960s, I bet there are families# that had difficulty reconciling about that. But back then, the political system# saw its job as managing. Leaders knew,## this is an incredibly diverse country,# rural versus urban, race upon race,## ethnicity upon ethnicity, religion upon# religion, sometimes men against women,## young against old, rich against poor,# all of these potential fault lines. And it's the job of the people who meet in the# buildings down the road here to manage t to say, we keep -- while everyone else is getting# excited, we keep our cool. And we remember th what is really important are dams and roads and# high schools and defense plants. And we're going## to make the deals based on that. And we're all# just going to lower the temperature at the center. But the political circle at the top no longer# sees these conflicts as dangers to manage.## They see them as resources to exploit. And Donald# Trump is better at this than just about anybody,## that they take this dangerous stuff,# and they say that is going to be not## something I'm going to try to contain,# but something I will use for fuel. JUDY WOODRUFF: What effect does# that have on today's divisions? DAVID FRUM: We will be more fractious,# we will be more argumentative, because## all the demons that exist in any society will# not only be liberated by t but will be encouraged, because Donald# Trump will be looking to his constituency## of very upset people in order to impose his# lawless will upon the constitutional system. I want to get away with Watergate. I want to# pardon myself. I want to fire prosecutors. I## want to do all the things that Nixon# did and many of the things that Nixon## never dared to do. And I'm telling you in# advance I'm followers to frighten the political# system into letting me have my way. JUDY WOODRUFF: And if Trump does use# the criminal justice system to shut down# investigations into his own conduct, including# alleged efforts to overturn the 2020 election,## the consequences will be dire, according to Frum. DAVID FRUM: The country will be in the# streets. Congress will be in an We will talk about nothing else. There# will be no other policy. no other topic. You won't be able to# accomplish anything. There will be## resignations from the Department of Justice.# There may be resignati It is going to be chaos, and# the chaos will never stop. JUDY WOODRUFF: And if, conversely,# Joe Biden wins reelection,## what happens to the current state of# our country, of our polarized state? DAVID FRUM: Sigmund Freud, the founder of# psychiatry, is supposed to have said that the## purpose of psychiatry is to convert hysterical# obsessive neurosis into ordinary unhappine If Joe Biden wins, we get all our# usual problems back, rich versus poor,## urban versus rural, climate change,# deficits, structure of world peace,## trade with China. Not a single problem# will be fixed, but we will have a working## set of institutions with which to address the# problems. And our disagreements won't go away. You will just have non-sociopathic,# non-psychopathic people saying, OK, the people## outside this room disagree a lot. We are going# to sit down at the table and find something we## can agree on, so that I can take something to my# people and you can take something to your people. JUDY WOODRUFF: No guarantee, however, that the# divisions among the American people would ease up. For the "PBS NewsHour," I'm# Judy Woodruff in Washington.
