As a foreigner I am surprised it took this long. Will likely not lessen the support for Trump, but nearly nothing will at this point.
As a foreigner who’s spent a lot of time in America, this may actually be good for Trump. I am not 100% sure how elections work in the US, but at most this will keep his name off a ballot Trump would never win and at best it will ensure his name has to be on every ballot. Assuming the SCOTUS overturns it, it sets a precedent that the POTUS is not an officer and therefore isn’t included in any legal language that concerns officers. Which opens up expansion of the powers of the executive. Still assuming that the SCOTUS overturns it it could play right into the Project 2025 playbook.
