It’s an interesting exercise to try to imagine what the Trump admin will look like 10 or 20 years from now. It could be that the most defining events of the presidency are yet to come. But given how I personally have had the experience of living through the Bush admin and it’s aftermath, and have seen how in hindsight and without partisanship goggles on, its possible for those on the left to actually acknowledge that president’s accomplishments without snickering, I do think a day will come when some things that Trump did, considered in isolation, will seem sensible. I’m not convinced he’ll be seen as a national disgrace, in the same way that Nixon is.
It’s really difficult to know, though, because I think the question of Trump’s legacy can’t really be addressed outside of the context of the post-Trump years, in a way that isn’t necessarily true of other presidents. Whether the post-Trump world brings about a paradigm shift that makes Trump seem like an important, pivotal transitional figure, or if things revert to some earlier Obama years-like state is quite relevant. Seems like the former is significantly more likely.
