he lack of evidence is not the biggest problem with this conspiracy theory, though. The biggest problem is that the theory’s most important underlying assumption—that Trump is anomalous, a xenophobic buffoon posing as a Republican—is wildly ignorant of actual Republican policies.
Boiled down, Trump’s appeal to the Republican Party’s base consists of his willingness to say nakedly racist statements and his promises to enact equally racist legislation. But why is that appeal surprising? In its contemporary manifestation, the GOP has repeatedly sought the support of voters who wish to disempower and intimidate racial minorities. This isn’t just about the party’s bizarre obsession with upholding the sanctity of the Confederate flag. To this day, for example, the party continues to advocate for Voter ID laws, which are ostensibly designed to combat in-person voter fraud—a virtually non-existent phenomenon—but in practice help prevent a disproportionate number of eligible non-white voters from actually voting. Its intellectual leaders have dismissed the ubiquitous threat of police violence towards black people as illusory.
Donald Trump’s popularity indicates that this country’s most fervent conservatives are primarily concerned not with reducing abortion rights, or repealing Obamacare, but rather with preserving white hegemony in the United States. For years and years, the Republican Party has happily accommodated these kinds of conservatives under the unspoken assumption that they would never be powerful enough to publicize their own candidate. Trump speaks to the error of that assumption.
In this context, the theory that Donald Trump is secretly helping Hillary Clinton get elected is not really about the Republican Party’s hostility toward Donald Trump or its habit of inventing conspiracy theories about Hillary Clinton. (Although both factors have certainly helped with its formation.) It’s the result of a major political party coming to terms, however illogically, with who exactly its supporters are.
Its not so much that Trump is crazier than other republicans or unelectable… its that he's direlty appealing to one of the nasiter bits of the base.... that they've been courting and building for years.
Eventually, something is going to have to give and the republican party is going to have to break in half between the reasonable side and the crazy zealot racist teaparty super religious side. That divided support won't win any national elections for a while, but it can still do fine on the state level. It'd be nice if the party could be sane and reasonable again instead of just... against everything that isn't rich white men.
