GOP is constructing means to extend minority white rule

There are many countries around the world where an ethnic minority has ruled over an ethnic majority for many, many years. Consider: South Africa, Syria, Liberia, Iraq, etc. Any place in the colonial era. There's a while Wikipedia article on the topic of a "Dominant minority". Republicans, fronted by the current President, are well on their way to instituting the means to do the same in the U.S.:

The move to denaturalize some citizens is just the latest in a larger drive by Republicans—led by key figures in the Trump White House—to preserve a white majority in American politics. At the state level, Republican lawmakers take steps to protect GOP districts, dampen voter turnout, and otherwise hinder participation, which raises the chances of Republican victories for Congress and the White House. In turn, Republicans in Washington nominate and confirm judges who give voter suppression the cover of law, giving incentive to new efforts at restriction and disenfranchisement. What Donald Trump brings is an explicit effort to write nonwhite immigrants out of the body politic, removing as many as possible and presenting the rest as a suspect class.
