That is a common misconception. If you look at actual policies the US is pretty far left in many ways. I spent a few days studying this a year or two ago, and the US is to the right of about 3/4 of Western countries, and to the left of about 1/4 of them.
It's a common misperception to believe there's actually an inch of a difference between democrats and republicans in terms of actual policies
that really matter. You could call them "republocrats" just as well.
In the background, they're basically a neocon one-party-system, owned and controlled by exactly the same forces.
All the differences are just propaganda or artificial pseudo-differences to create the illusion of differing principles, divide the people emotionally and infuriate them over meaningless issues.
The US policies combined make it easily one of the most ultra-right-wing extremists on the entire planet, in terms of resulting effects they are literally second to none in that respect.
