See, I told you so! ThIs is the establishment response to #NeverTrump, vote for that Saphic Succubus you stupid sons of bitches because Trump is unprofessional! Seriously, If being a corrupt piece of lying sh*t is "professional" then who but a complete f**king moron would want a "professional"?!
Pablo is right, they all need go f**k themselves!
ETA - This is what "professional" looks like.
Yes, and this gets at the heart of why they've always hated their own base. When the Tea Party became a mass movement after the Obamacare chicanery and swept them into a House majority in 2010, was their response "this is a whole new electoral powerhouse we can harness to change the partisan dynamic"? Hell no. It was McCain calling us hobbits and whacko birds. They'll take our votes at election time, and browbeat us if we waver at getting behind their candidates, but after that it's "Now kindly STFU and STFD, this government belongs to
us you dumb hicks!"
It's a Gentleman's Club to them, where they bask in each other's regard. Being collegial and even tempered with nicely creased trousers (translation: capable of delivering eloquent concession speeches) while giving due deference to the correct lobbyists and business interests (translation: one big financial circle jerk) is what matters to them. Minority status and cultural irrelevance is fine with them, it's simply the role they've been assigned to play in this theater.
They are more threatened by populist uprisings from within their own party than they are the actual opposition party. Instead of harnessing the power of the uprising, which would require acquiescing to some of its demands, they'd rather just stamp it out even if it means actually joining with the other party.
Trump is popular because he has some fight in him. He doesn't silently take the barbs from the left wing media. People are prepared to overlook a lot of the concerns about his candidacy simply because he knows how to punch back, and the conservative electorate is absolutely starved for such a candidate. General Patton said something along the lines of "an imperfect plan executed boldly beats a perfect plan executed timidly" and that, in a nutshell, is what drives the Trump phenomenon.
