As someone coming from Norway, I can guarantee you that Biden would absolutely not be considered left, or even center, on the Norwegian scale. So for me (who is left on the Norwegian scale), there is -plenty- of room to his left for him to go to.
(And yes, T***p is still 10 000X worse.)
As someone from Norway, but who has also lived in the united states for over a decade, I can assure you that it is 100% correct. He might not be particularly far right, but he is absolutely not a leftie.
