The U.S. is only center right because Republicans are almost right-wing extremists.
The center-right has been failing America since Nixon and Reagan.
America has been its best when overwhelmingly led by those left of center. Stop believing «Republican» bullshit.
I regret* to inform you that America is basically a center-right country, and that's the sweet spot of liberal constitutionalism (if we could stop buggering it up)
*I do not regret it
