For the past 15, many in the Alt-Right writ large have pushed what is known as "The Sailer Strategy." Put simply, the GOP is the White People's Party (whether it likes it or not) and it should engage in "in-reach" to Whites as opposed to "outreach" to minorities.
N.B.: No disrespect to Steve Sailer, but if this strategy should bear anyone's name, it is Sam Francis, who wrote about this explicitly and definitively in the 1990s. So I'll call it the Francis Strategy to pay respects to the great man.
First off, at this point, The "strategy" seems more descriptive than prescriptive. The GOP has been winning as the White Party—more so, the Working White Man's Party—for decades. Indeed, Cucks mastered the art of being implicitly White and explicitly libertarian or non-racial.
Secondly, this strategy has not benefited Whites. Working Whites vote for the GOP consistently—and have begun to passionately hate Democrats—but this has not led to legislation that would actually help them. (This goes well beyond immigration).
Republican power in Congress and the Presidency has coincided with the "White death," demoralization, breakdown of family formation, indebtedness and more. It's tragic. (I praise Tucker Carlson for talking about this, though not always in the best ways.)
The thought has crossed my mind that the GOP becoming the White Party has a sinister element to it. Whites are turned off by the Democrats more and more and come running into the arms of GOP cucks and conmen. In the end, the GOP isn't the Stupid Party—but the Evil Party!
After the Midterms, many Alt-Right commentators yucked it up about how Blacks didn't flood into the GOP, as grifters like Candace Owens promised. Apparently, only Whites can maintain their ongoing cuckoldry by Republicans!
Lastly, Donald Trump has not expanded the White voting base; in fact, he's shrunk it. In 2016, Trump made inroads with every racial group save one—Whites. He won fewer of us than Mitt Romney. In 2018, 54% of White voters chose Republican, down from 60% in 2010.
Trump's problem is that his stupidity and bombast turn off suburban, educated Whites. And despite his popular rallies, how many working class Whites are demoralized by the fact that their lives are simply not getting better, while Trump is out bragging about the stock market?
