There is only one kind of political brain more mysterious than that of a liberal, that of so-called "moderate" (aka Rino) Republicans. This sub-species is a somewhat inexplicable form, from an ideological perspective ; they insist on identifying as a Republican but, more often than not, espouse liberal views. They only loath the right, chum with liberal Democrats, seek praise from their culture elites and their MSM press, and are terrified of being seen as unfriendly to illegals, identity grievance groups, and Democrats.
However, the source of their quisling personae does not stem so much from ideology as from social snobbery and bigotry; their comfort zone is to attack their own for being racist, unsophisticated, white and working class. Nothing is more horrifying to them than being in the same party as church-goers, pro-lifers, blue collars, and tea party newcomers and the common white guy. And nothing is more perplexing to them than ideology, someone actually having systemized beliefs.
Thus, the GOP Moderate RINO feels more comfortable doing the dirty work for liberals in eliminating serious rightwing opposition to Democrats and liberals. Indeed, as this seditious species has shown in 2008 they even vote against other RINOs (McCain) in order to jump on the trendy liberal racialist bandwagon of Obama (e.g. Powell, Brooks) ...and yet, they still assert they are Republican.
So no, they don't obsess over folks they tend to agree with (AOC or Hillary Clinton), but they do obsess over bashing the Tea Party, protecting illegals, and currying favor from Democrats.
And as long as a moderate Republican thinks "full control" of the Senate is possible with a mere one or two vote majority, with guys like McCain killing Republican reform efforts of Obamacare, and Democrats filibustering, then such RINOs will always be reviled as delusional snakes and 5th columnists.
Even though I am an agnostic, I leave you with a bible quote I have always found to good instructive to conservatives regarding the nature of moderate Republicans:
"I know thy works, that thou art neither cold nor hot...So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth."
