Sure, I’m from the US as well. In our case, I think this stems from multiple problems—the popular understanding of the constitution and the letter of the thing have diverged, and also the Supreme Court has gone in a third totally unrelated direction. So it becomes a convenient rhetorical meme. (IMO, we should the thing once a generation and have the populace re-ratify it with a high consensus, so we’re all on the same page).
I’m not sure if that’s the case in Germany though.
as the constitution doesn't have that high of a place in our identity it's more something for constitutional lawyers and higher courts. I think there's more tension between our constitutional law and that of the EU's law. for most people that's background noise I guess.
