"You have, then, the calm conservatism of George H. W. Bush and the fevered conservatism of Patrick Buchanan; the balm of Jeb Bush and..."

"... the bluntness of Donald Trump; the moderation of Theresa May and the flamboyance of Boris Johnson; of Angela Merkel, perhaps the most properly conservative of our contemporary leaders, against the radical outliers of reactionary German nationalism. Fawcett sees this as the core conflict within the right, always present, forever waxing or waning, and central to the future of Western democracy."

Writes Andrew Sullivan, in a NYT review of "CONSERVATISM/The Fight for a Tradition" by Edmund Fawcett. Fawcett calls himself "a left-wing liberal."

The quote I cherry-picked has Sullivan contrasting the conservatism of Edmund Burke — who "believed in pluralism, modest but necessary reform and the dispersal of power" — with the conservatism of Joseph de Maistre — "who found adaptation to modernity to be indistinguishable from surrender" and "saw decline everywhere and always, enemies within and without."

I'm struck by the silliness of the phrase "the balm of Jeb Bush." 

Sullivan makes the contrast between moderates and radicals sound like a matter of physical heat. And the best people are the ones whose nature is to remain cool. This distaste for "flamboyance," "bluntness," and "fever" is openly elitist — as we see in the last paragraph:
Moderate conservatism is a vital counterbalance to liberalism, as the Trump years have shown. For it to disappear into a populist cult, hostile to democratic norms, contemptuous of all elites, captured by delusions and sustained by hatred and ressentiment, would not be completely unprecedented. But, unchallenged by moderate conservatism, populist or “hard right” conservatism will be deeply destructive. In that sense, the battle for moderate conservatism is now inextricable from a battle for liberal democracy itself. 

IN THE COMMENTS: hawkeyedjb says:

Liberals pretend to respect Moderate Conservatism, but when a moderate conservative like Mitt Romney comes along, they turn him into an evil, money-grubbing, cancer-giving Hitler youth. Just one example out of many that comes down to the same thing: all Republicans, of any stripe, are Hitler in the end. So why not be Trump?
That's a different perspective on what — to use Sullivan's phrase — "the Trump years have shown."
