I’m probably gonna get downvoted to hell for this, but I’m just gonna say it. Far left and far right more or less do not exist in the US as far as political parties are concerned. It all floats from barely left of center to moderately right. Again, this is the parties and not necessarily people. As far as parties are concerned, we don’t experience the real extremes in the US. For this viewpoint of “extremes”, I squarely blame Ted Turner for inventing the 24/7 news cycle which has enabled the two major parties to label the other as an extreme.
I guess that is part of my point. We only have two major parties and they have both tried to present themselves as polar opposites when that is not the case. ETA: The European and US ideas of left and right (especially concerning conservative vs liberal) are very, very different
