I'm not an American. I think your constitution basically sucks, with the mitigating factor that it was very practical and relatively democratic compared to other states at the time it was written.
One of the huge criticisms that I have is that you can't get rid of an administration. Impeachment seems to be virtually impossible, whatever Trump does or did. And even then you get a vice president who ran on the same ticket and profited from the same criminal behavior.
In Germany, we can get rid of the chancellor within days or weeks, depending on the procedure. We also can't have split governments sabotaging everything. Every vote counts the same etc.
