The problem with trying to read things into the results of the 2024 election is that they’re totally in line with a global thrashing of incumbents that occurred that year. Incumbents in the US actually did better than the average.
Humbly, I think this thinking is part of the problem. The incumbents were crushed because they mostly all copied each other and are seen as part of the same system. There are Western parties which have behaved differently and were not crushed. It wasn't just a meteorological event.
