That's because they -- to use what they would consider librul jargon -- feel empowered, emboldened, encouraged. His belated demurrals make the indecent feel embraced, as if he's speaking to them in a code only they can understand, while the rest of us are left bemused, bewildered.
This is what they count on, what they subsist on. They're not even bothering to hide behind some book or Austrian economist or some such. This is pure fuck you, whaddaya gonna do about it?
And you know what? They have a point, however demented it may be. How's that "when they go low, we go high" shit been working out for everyone? Look at your state house, your congressional reps, your executive and judicial branches. They drank our milkshake while the Democrats were haggling over bathroom rights. Awesome.
Most of all, this is proof positive that Fuckface Von Clownstick is merely a symptom; the Republican Party is the end-stage (as Charlie Pierce puts it) prion disease that comes from eating the monkey brains. Clownstick is the culmination of decades of work, and as such, even if we find a way to get rid of his incontinent, doddering ass, they'll just find a smoother, sleeker version to pimp the same asshole message.
But the main point is this: they are able to simultaneously buy the premise that the country is a flaming hellscape needing serious expertise to repair it all, and hand the job over to a moron who is months away from smearing his old-man, KFC-smelling poop all over the Oval Office walls. There is truth to the idea that a sophisticated mind can hold two contrary ideas at the same time; this becomes inoperative when both ideas are completely awful and stupid.
This is where, once again, we may collectively want to look past the current threat of Clownstick's ape-like mendacity, and realize that he's simply the current avatar of what that entire party is thinking, and we'd better get with the program fucking quick-like, or they're going to finish that steamroll job they've been doing. Fuck these assholes; fight or die.
