Gosh, I just fundamentally disagree with this.
For starters, foreign policy. Trump's foreign policy leans towards the isolationist. I won't say that it's explicitly that -- I think that would be an exaggeration. But it certainly has those overtones. It's unimaginable to me that Reagan would have, for instance, been the least bit hesitant to provide all the military aid he could to Ukraine to help stanch Russian expansionism. I realize that Trump's line is that it "never would've happened had he been president" and that he'll "solve it in 24 hours" (or words to that effect). But the former is counterfactual musing based on his inflated ego, the latter is just idle bravado bullshit. It reminds me of the old adage that the quickest way to end a war is to lose it.
Second, trade. Trump is almost certainly the most protectionist president we've had since the onset of the Great Depression. And this absolutely is part and parcel to his populist economic message. It is absolutely true that many peoples' livelihoods have been negatively affected by free trade. And I'm not going to blame an opportunistic politician for trying to make hay out of that. It's low hanging fruit -- especially when elections are being won and lost in the Rust Belt. Michael Moore was absolutely spot on about this when he predicted Trump's victory in 2016.
But however potent this narrative is politically, nobody should confuse it with anything Reagan stood for. Free trade, like any other economic policy, has its trade-offs. But there is absolutely zero question that it's a net positive for nations that practice it. This is one of the biggest reasons Javier Milei has been such a breath of fresh air. The guy gets it.
Ultimately, though, populism is about framing elections as an epic struggle between normal people and some powerful entities. In Trump's case, and in the case of many of his supporters, that entity is often summed up in the term "globalists."
Can anybody imagine Reagan (or any of those who came up more or less in his image) utilizing this kind of a political appeal? Because I certainly couldn't.
