Curious which American election observers are neutral parties then, if you refuse to believe that the Carter Center is unbiased. Because I’ll bet you I can use similar mental gymnastics to tie every single American election observer to one side or the other (or even both, just for fun).
There are some commercial rolls I’ve seen in the US that seem to be a happy medium…the holder itself in the stall has a thin plastic rod for the TP to go on, and the rolls have a very small opening in the center (and no cardboard) to go on that rod.
