He's benefitting from three main things right now in my view.
1. People are realizing he's full of shit on tariffs, so while the market fluctuations are making SOMEONE filthy rich, the concerns he'll lead us into a depression are diminishing and the markets are remaining "relatively" stable.
2. Border encounters are way down, which people are interpreting as Trump closing the border. I'm not convinced that's what's actually happening, but if it is, it will be interesting to see what happens once we get a little further into the agricultural season.
3. He smartly kicked Elon and DOGE to the curb. All the "principled" conservatives who were hoping he'd be a good fiscal steward will now be predictably disappointed as he exploded the deficit further with his tax cuts, but DOGE had become extremely unpopular and it's now effectively mothballed.
I for one am very glad that Trump's bark has been much worse than his bite so far. He's still the last person in the world I'd want leading this country, but I do think there's more reason to hope he'll be constrained by public opinion than there was a couple of months ago. That said, our margin for error is about as slim as it could possibly be right now, and it wouldn't take much to send everything spilling over the edge. The odds are extremely high we'll be in a much worse place a year from now than we are at this moment.
