Human rights are an ineffective policy -I notice that you portray no genuine commitment to human rights, human freedom, and democratic principles in your post.
Which is why you, the Kremlin, and the KGB prefer Republicans.
Liberals - like Jimmy Carter, et al. - have an ideological and personal predisposition for being hostile to totalitarianism, repression, and all affronts to human dignity and freedom.

It's shortsighted and ineffective to to do anything except realpolitik.
we can back UN sanctions etc, but it cannot drive bi-lateral relations
