Is Trump's Candidacy a Conspiracy Against the Republican Party?

After racist generalizations against Mexican immigrants, cavalier dismissals of the idea that John McCain could be considered a hero in service to the U.S. for suffering years as a North Vietnamese prisoner of war, a litany of grotesque allusions to the enormity of his personal wealth, and his continuous articulation of vacuous, overly simplistic criticisms of existing governmental policies on a range of issues absent any clearly defined policy alternatives, Donald Trump has apparently decided to use this moment in the vetting out of Republican Presidential candidates to introduce a novel and refreshingly frank species of misogynistic prejudice, attacking, of all women, a Fox News personality popular among its conservative, Republican-leaning viewer base!?  Isn't there something amiss here?  Trump is hammering home a cavalcade of all the far right wing racist, sexist, and classist prejudices latent within the political unconscious of the Republican base, unvarnished by the slightest hint of political correctness, let alone decorum or a basic sense of interpersonal sensitivity or human decency, and, for all his efforts, he's apparently still number one in all of the major polls of announced Republican candidates!  There is something that just makes me want to ask who put him up to this.  This can't be for real!  It sounds more like a Stephen Colbert piece off of the Colbert Report, run amok for an audience that just doesn't get the joke, or, more to the point, it harkens back to Seventies television, when conservatives could enjoy big laughs from "All in the Family" while liberal intellectuals could laugh at the caricature the show made of conservatism.  Trump is playing Archie Bunker for millions of Republican conservatives who just don't get that they are the butt of the joke, and that, if the Republican Party does not get its act together and select a serious candidate who can appeal to a much broader, culturally heterogeneous electorate with a moderately conservative agenda and a willingness to engage in principled compromise with progressive constituencies, then the country is going to elect another Clinton into the White House and, probably, at the same time, bounce one if not both houses of Congress back to the Democrats!
