This impression has strengthened quite a bit in recent years as it’s become clear that political movements and politicians that are diametrically opposed to the teachings of Jesus are perfectly okay if they align on other more immediate secular political issues.
There’s always been a claim that the US is an outlier compared to other developed nations in terms of religiosity. I don’t really believe this anymore. I think we have a lot of politics with heavy religious veneer, but if you look only at sincere belief in the tenets of a faith I don’t think the US is much more religious than the UK for example.
