Let's view this sentence in bold.
"The Democratic machine does not need a tune-up—it needs a complete overhaul."
Has he quit yet?
Donald Trump Is Not Too Big to Fail, by Gary Younge (The Nation)
His victory illustrates the weakness of the Republican Party, not its strength. And despite his braggadocio, he’s vulnerable.
... Fortunately, while the right is emboldened, it is not ascendant. Trump’s victory illustrates the weakness of the Republican Party’s leaders, not their strength. They wanted anyone else, and now they are unable to control him. He openly derides and baits them. Notwithstanding his braggadocio, he remains vulnerable. His agenda is no more unassailable than his victory was unfathomable.
But there is nothing inevitable about his demise. If the liberal left is going to challenge him effectively in the coming years, then it must learn the lessons of its defeat. The Democratic machine does not need a tune-up—it needs a complete overhaul. For far too long, it has been too arrogant, complacent, or contemptuous (and sometimes all three) to make an argument beyond “at least we’re not them.”
The reason why Trump was able to attain power is not because he had better ideas, made better arguments, had greater organizational capacity, or even spent more money. The reason he was able to win was because those charged with opposing him offered not hope, but the status quo, in a country where inequality between rich and poor and black and white is growing. He won because his opponents believed their own PR. Hubris sent them to Arizona when humility would have kept them in Pennsylvania. He won because, emerging from a period of economic crisis, the multimillionaire businessman whose catchphrase is “You’re fired” looked less like a representative of the establishment than the liberal who claimed she represented the interests of the poor. If he is stupid, then what are we?
