I suspect one reason Trump horrifies so many conservatives is not because they suspect he's a closet liberal, but because they're terrified at the possibility he's not just a conservative, but an effective conservative. They would rather lose, and lose big, than have Trump be the model of a conservative victory - loud, obnoxious, offensive and shameless.
First, because Trump is a political actor without the standard chains on; the Chamber of Commerce can't harm him with his base by denouncing him (far from it.) The ADL can't do him harm by wringing its hands and announcing their concerns that Trump is an anti-semite (very far from it.) A conservative is one thing, but a conservative who isn't leashed by mainstream bloggers, Foxnews and CPAC? That's full-blown Frankenstein territory, and it only gets worse when one realizes that Trump's able to crack a rhetorical whip and do some damage of his own. Obama's a belligerent little priss, but even he has chains - they're just liberal chains.
Now, that would explain the fear of Trump at the higher levels - one we're talking about popular bloggers, special interest groups, lobbyists and more. But then why the fear of Trump at the lower level?
I think part of that - not all of it, but part of it - is that they simply don't want success to even be possible in this package. I'm reminded of some of the shit Ed Feser got when he published The Last Superstition - why, he was polemical at times, how horrible. He insulted people! Sure, they were atheists, and nasty ones at that, but... shouldn't we be better than that? Because... well, we don't feel right being polemical. We don't like to insult.
Because insulting is dangerous, and we may get insulted back, and we may well be outgunned. Better to insist it's all out of bounds and hope like hell the referee will step in, because otherwise we're in trouble.
Obviously, I have a different view about that. I like the new political culture, which doesn't deal with BlackLivesMatter by trying to ignore their existence or kowtowing to that idiot Al Sharpton in some hopes of buying credibility with blacks. I'd rather they just be called thugs who should be arrested or who may well in fact deserve a punch in the head, and instead address blacks at large directly. I'd rather see Fauxcahontas mocked openly instead of idiot conservatives pretending that what the people really want to hear is praise of her many accomplishments (Good God she's a woman, and she finegled her way into academia no less) and laughing in her face at her antics is off-limits. I'm willing to live with the new, more upsetting world, especially since the world I was actually getting was as bad anyway, just with the targets limited to my side of things.
I understand that many conservatives do not like this, and want - desperately, frantically, with sweat now pouring from their brows - to go back to the world where being meek was called being noble, and being a coward was called being sensible, and being bland was preferred to being insulting. I'm sorry, but that ship has sailed. We now live in the world where Donald Trump is the most persuasive articulator of patriotism around, and Milo Yiannaopolous gives the best critiques of the LGBT movement, and Vox freaking Day is the one talking sense about culture, not PJ O'Rourke.
I have a feeling these guys are here to stay this time around, so best get used to 'em.
