It's quite simple, and aligns with why he got in in the first place.
The economy and cost of living is still in the toilet. Trump is a protest vote because competent public servants have failed to even acknowledge that everything costs 2-3x what it did a decade ago. Sad to say, but most people don't give a fuck about LGBTQIA+ rights, Israel, Ukraine, or anything outside of this.
Call it apathy if you want, but it's ultimately a failure of moderates to acknowledge a better social net for people (I.e. left policies) or propping an economy by improving lives for regular people so their money goes further.
I don't mean this in a horrible way, but a lot of people on here are extremely entitled when it comes to immigration.The US is an incredibly hard place to move to, even if you are a skilled worker. While it often is easier to move into Europe or Canada, it's not a given that you can just walk into any of these countries and expect to live there. Immigration is hard!
