I agree. Of the two major US political parties today, one is primarily radical right with a small conservative branch that is struggling to stay in their party. The other is conservative to moderate with a small liberal branch that is fighting to make their party stand for something.

That liberals are the left wing in US is quite telling. In Europe and Latin America liberals are (center-)right.

The word "liberal" means different things in different places.

Maybe, although many policies by European liberal center-right parties are to the left of US liberals.

The main reason is probably that US never had the major socialist movements of 20th century Europe. Before those liberals were the left in Europe too.
