I doubt anyone is surprised by another plausible case of corruption (or depravation / or pedophilia if you address the other allegations). There is also the story that the FBI was sitting on this since December (potential for blackmail in case Biden is elected? who knows) which is scary as well.

In the end, I think it's endemic in having human corruptible politicians who can accentrate power. We will minimise this problem only if we decentralise the structure of powers in our society.

Not that any mainstream party has an interest in promoting that (unless you consider Jo Jorgensen and the libertarian party)
