Yes, but at some point it doesn’t matter. The AI is trained to replicate human writing. There will be a point where it becomes so good that the result is a perfect replica, where it is indistinguishable from human text. I.e. even a perfect detector will not be able to confidently declare it as AI written, not ever. Because there is no difference.
The election system distorts the vote quite dramatically in the US, that’s true.
However, depending on where you’re from left has quite a different meaning from what Americans mean when they say left. E.g. the Democrats don’t want to dismantle capitalism or expropriate real estate companies (the city of Berlin seriously looked into this option). Center left has a similar shift in meaning in other countries.
